• Storage keys are now unique per widget. Twelve widgets from the previous batch shared a single localStorage key, so two of them on one page could overwrite each other's entries. Each now writes to notion-arena.<slug>.v1, and scripts/check-widgets.mjs fails on a key that does not match its file name or that another widget also claims.
• All twelve additions are free, offline, and browser-local, bringing the catalog to 155 components: 144 widgets and 11 native recipes. Local storage is not encrypted; use approved shared systems for sensitive data, permissions, audit history, or official records.

• Community and production: Volunteer Hours Log and Film Shot List. Hours are unverified manual estimates; the shot list stores no footage, releases, crew records, or publishing state.

• Funding and commerce: Nonprofit Grant Tracker and Ecommerce Margin Estimator. Amounts are manual USD entries and arithmetic only; there is no eligibility, compliance, tax, currency conversion, or financial advice.
• All twelve additions are free, offline, and browser-local, bringing the catalog to 119 components: 108 widgets and 11 native recipes. Local storage is not encrypted; use approved shared systems for sensitive data, permissions, audit history, or official records.

• shadcn/ui-compatible registry at /r/index.json, /r/{name}.json and /r/schema.json, with widget HTML inlined rather than linked.
• POST /api/install with a plan mode that requires no credentials and returns the full ordered request sequence before anything touches your workspace.
• Every widget implements the same configuration contract: baked-in JSON, query-string overlay, declared-parameter whitelist, and universal theme and accent controls.

Ten more taxonomy widgets for time, learning, and operations

• Time tools: Event Count-Up and Interval Timer; location display: Sunrise & Sunset, calculated approximately from configured coordinates, date, and time zone.
• Personal tools: Daily Routine Checklist and Workout Set Tracker, with browser-local state; the Manual Currency Converter uses a rate entered by the user, not a live feed.

• Operations tools: Local Ticket Queue and Local Asset Checkout. Their state stays in this browser and provides no team sync, permissions, or audit trail.
• This brings the catalog to 49 components: 38 widgets and 11 native recipes. All ten additions are free, self-contained, and offline. Use a Notion database or a connected service when data needs shared access, a system of record, or external freshness.

• Time tools: Stopwatch Timer, World Clock Board, Year Progress, Date Difference Calculator, and Moon Phase.
• Learning tools: Reading Progress Tracker and Spaced Repetition Deck, with browser-local progress and schedules.
• Operations tools: Monthly Budget Planner, Inventory Counter, and Local Intake Form. Budget and stock edits remain in this browser; the form prepares copyable JSON and sends nothing.

Month Calendar

• An offline, read-only month grid with previous and next navigation, a jump-to-today control, selectable dates, and an agenda panel.
• Optional dated notes are supplied in widget config. The calendar does not read or write Notion data, sync with external calendars, or send network requests.
• Use a Notion database calendar for collaborative schedules. Keep private event details out of public embed URLs.

Wellbeing and study widgets

• Water Intake Tracker: one-tap daily logging with a goal ring, undo, date rollover, and browser-local state.
• Breathing Timer: box, 4 7 8, and equal-breathing patterns with pause, resume, reduced-motion support, and no sound.

• All three are self-contained, work offline, and do not write to Notion or sync local progress across devices.

Visual components

• Whiteboard: pan, zoom, freehand, shapes, sticky notes, and SVG export. State persists locally under notion-arena.whiteboard.v1.
• Org chart: delimited-string data model, collapsible branches, JSON and SVG export.
• Both export through the clipboard and always log the payload as a fallback, because clipboard writes need a user gesture and some WebViews block them.

Planning components

• Mini kanban with drag between columns and localStorage persistence.
• Gantt timeline with day-level positioning, dependency-free layout and a today marker.
• Eisenhower matrix with a seedable quadrant model via URI-encoded JSON.

Ten more offline widgets for personal planning and everyday tools

Twelve offline components for home, finance, study, and reference

• Home and travel: Packing List, Household Chore Checklist, Pet Care Checklist, Plant Care Log, and Home Maintenance Log. Their entries remain in this browser, not in a shared household workspace.
• Pet, plant, and maintenance widgets are personal checklists or logs, not veterinary, plant-care, repair, or safety guidance.
• Finance: Expense Tracker totals entered expenses for the current month; Savings Goal Tracker, Net Worth Snapshot, and Manual Portfolio Tracker calculate from figures entered by the user. No bank connection, live prices, or financial advice.
• Study and reference: Class Timetable, Bookmark Library, and Reading List are local-only. Bookmarks accept http and https URLs, fetch no previews, and open only after a click; schedules and reading metadata are not externally verified.
• All twelve additions are free, self-contained, and offline, bringing the catalog to 71 components: 60 widgets and 11 native recipes. Use Notion databases when the records need team access, permissions, or sync.

Twelve more offline tools for learning, planning, and visualization

• Learning and reference: Assignment Tracker, Exam Planner, Study Session Log, Research Log, Glossary Builder, and Daily Journal. Coursework, notes, and journal text remain in browser-local storage; journal content is not encrypted, so avoid sensitive details.
• Meeting and project planning: Meeting Agenda, Decision Log, Action Item Tracker, and Project Risk Register. Entries are local drafts without team collaboration, reminders, approvals, or an audit trail; risk scores are simple qualitative priorities, not forecasts or professional evaluations.
• Visualization: Chart Builder plots manually entered values, and Concept Map Builder draws a small one-level personal diagram. Research links are user-entered http or https URLs with no fetching or previews.
• All twelve additions are free and offline, bringing the catalog to 83 components: 72 widgets and 11 native recipes. Use a Notion database when records need shared access, collaboration, or sync.

Twelve offline tools for research and creative production

• Research and writing: Course Notes, Literature Review Matrix, Lab Notebook, Protocol Checklist, Idea Inbox, Manuscript Progress Tracker, Chapter Outliner, Character and Setting Bible, and Submission Tracker. Notes and outlines stay in browser-local storage, which is not encrypted; the research tools do not verify sources or create regulated records.
• Podcasting: Podcast Episode Planner, Guest Prep Sheet, and Episode Production Checklist. Guest links are user-entered http or https URLs and are not fetched; nothing is published or sent.
• All twelve additions are free and offline, bringing the catalog to 95 components: 84 widgets and 11 native recipes. Manuscript Progress stores counts only, not manuscript text; use shared Notion databases when collaboration or permissions are needed.

Notion ships HTML blocks and the Views API

• HTML blocks become installable through the API: reserve a file upload, send the bytes, append an embed block referencing the upload id.
• POST /v1/views lands, making board groups, timeline dates, chart axes, calendar ranges and form questions creatable from code for the first time.
• heading_4 and tab blocks are added; position replaces after for child placement; notifications gain a silent mode; database objects gain a typed database_type.
• This is the version every request in Notion Arena pins, and the reason native recipes can provision a workspace end to end rather than stopping at the databases.

Notion adds dashboard view caps, confetti and AI formulas

• Dashboard views gain a widget cap per view, which is why recipes create each chart as its own view rather than assuming an unlimited grid.
• Dashboard layouts remain read-only through the API: you can create the view and its widgets, but Notion composes the arrangement.
• Native button and automation coverage still has no public endpoint, so recipes continue to ship those as documented manual steps.
