Productivity Toolkit Tampermonkey Script

Productivity Toolkit is a local-first Tampermonkey userscript that adds a small browser productivity suite to normal websites. It keeps settings and user data in Tampermonkey storage and does not require an external server or cloud service.

Github: https://github.com/Thomas2074/Productivity-Toolkit/tree/main

Current version: 0.2.8

Features

  • Tucked toolbox-icon side tab that slides out on hover or keyboard focus
  • Draggable toolkit panel
  • Saved light and dark mode for the toolkit UI
  • Text expander for inputs, textareas, and basic contenteditable fields
  • Local quick notes with autosave and .txt export
  • FocusLock site blocking with manual sessions and recurring schedules
  • Pomodoro timer with side-tab countdown and completed-session tracking
  • Domain-level visible-time tracking with daily and weekly reports
  • One-click page highlights for selected text or typed phrases
  • Editable keyboard shortcuts
  • Per-site toolkit and feature enable/disable rules
  • Full JSON backup and restore

Privacy

The script is designed to be local-first.

  • Data is stored with Tampermonkey APIs: GM_getValue, GM_setValue, and GM_deleteValue.
  • The script does not intentionally send notes, snippets, reports, settings, or browsing logs to external services.
  • Time tracking is stored by domain, not full URL.
  • Password fields are skipped by the text expander.
  • The project avoids credential storage, password management, and identity autofill.

Installation

  1. Install a userscript manager such as Tampermonkey, Violentmonkey, or a Safari-compatible userscript manager.
  2. Open productivity_toolkit.user.js.
  3. Copy the full script into a new Tampermonkey script.
  4. Save it.
  5. Visit any normal http:// or https:// website and click the tucked toolbox tab on the right edge of the page.

Default Shortcuts

Shortcut Action
Alt+Shift+P Open or close the toolkit panel
Alt+Shift+N Open notes
Alt+Shift+H Highlight selected text
Alt+Shift+C Clear highlights
Alt+Shift+F Start or stop a focus session

Shortcuts can be changed from the toolkit's Shortcuts tab.

Project Structure

productivity_toolkit.user.js  Single-file Tampermonkey userscript
README.md                     Project documentation

The userscript should remain single-file unless the project direction changes.

Development Notes

  • Keep all core functionality in productivity_toolkit.user.js.
  • Prefer Tampermonkey storage APIs over browser storage directly.
  • Avoid external dependencies unless absolutely necessary.
  • Keep UI styles scoped under the toolkit root IDs/classes.
  • Be careful with event delegation so checkboxes and form controls keep native behavior.
  • Avoid duplicate intervals, duplicate panel instances, and duplicate toast actions.
  • Avoid injecting into iframes and cap expensive page scans so the toolkit stays responsive on large pages.
  • Bump the userscript @version and internal APP.version when changing behavior.

Recommended manual checks:

  • Panel opens, closes, drags, and resets position.
  • Tucked toolbox tab is visible, slides out on hover/focus, and opens the panel.
  • Light and dark mode toggle correctly and persist after reload.
  • Notes autosave and export.
  • Snippets add, edit, delete, filter, and enable/disable.
  • Text expansion works in text inputs, textareas, and simple contenteditable fields.
  • Password and number inputs are not modified by text expansion.
  • FocusLock starts, stops, blocks listed domains, and respects schedules.
  • Pomodoro starts, pauses, resets, and updates the side-tab countdown.
  • Reports render today and current-week data, then export CSV.
  • Highlights can be added and cleared.
  • Shortcuts can be captured and reset.
  • Site rules can disable individual features or the full toolkit, then re-enable it.
  • Backup export works, valid backups restore, and invalid backups do not corrupt settings.

Known Limitations

  • Browser autoplay policies may prevent the Pomodoro completion beep.
  • Userscripts cannot run on browser-owned pages such as chrome://, edge://, extension stores, and some built-in PDF/new-tab pages.
  • Contenteditable expansion is intentionally conservative and works best in simple editors.
  • Highlighting is designed for ordinary article/documentation pages and may avoid or limit very large or complex DOMs.
  • FocusLock blocks by domain and subdomain matching, not by full URL path.
