Progress
Progress is the idea TasksPage is built around: instead of a task being either open or done, each one carries a percentage you set yourself. A 40% task is honest about where it stands, and a glance down the column tells you how far the whole day has come. Progress is free for everyone and works the same on desktop and phone.

Set progressDrag the progress bar — snaps to 5%.
Exact valueDrag the % number up/down to scrub, or click it and type. Mobile: tap the % and type.
From a checklistWhen a task's note has checklist items (the ☑ button in the note toolbar), its % follows them: ticked items ÷ all items, rounded — three items give 33, 67 and 100%. Question lines and plain lines don't count. While there is a checklist the % shows a ☑ and can't be dragged or typed; remove every checklist item and the % is yours again, starting from its last value. Not for repeating tasks: their % stays manual. Free.
SortClick a column header to sort by it; click again to reverse.
Auto-sortTasks sort by progress inside their section, so the ones closest to finished sit together and the untouched ones stay visible at the bottom.
100% is not done yetA task at 100% stays where it is until you complete it with the checkbox or the flame; then it moves to Done and can be undone from there.
Mobile stripOn a phone the progress bar becomes the thin strip along the bottom edge of the card; tap the percentage to type an exact value.
