Quadrant - a quiet todo grid

About

A four-quadrant todo matrix that lives in your new tab page. Drag tasks between quadrants, set deadlines, see what's coming up on the calendar, and customize everything to fit your workflow.

It can be used as an Eisenhower matrix, or as an Action Priority Matrix, or simply just a tool to track your todos in 4 categories.

Features:
- Four quadrants - categorize tasks by type (default: Work, University, Personal, Misc)
- Drag & drop - move tasks between quadrants instantly
- Deadlines - assign a due date to any task with a visual picker
- Calendar - click a date to see tasks due that day and filter the matrix
- Upcoming list - see the next 8 deadlines at a glance
- History - completed tasks go to a slide-out sheet where you can restore or permanently delete them. Tasks are stored on your PC, nothing gets uploaded anywhere!
- Customizable labels - rename the four quadrants to anything you want (Settings in the ... menu)
- Quadrant colors - set a background color per quadrant
- Page background - change the entire page's background color
- Backup & restore - export/import your tasks as JSON (merge or replace)
