Replace your Safari new tab page with a kanban style todo manager.

• Manage todos all in one page
• Drag & Drop between lists
• Create new lists for todos, as many as you like
• History: Cleared todos will be saved in editable text.
• GitHub-like contribution chart

Release notes:
- New feature: waterfall layout in drawer.
  - New feature: support auto timestamp when cleaning checked todo into history.
  - Some small UI polishing. 
  - Fixed a bug that drag&drop project list glitches when lists overflow the browser window (in Safari).
