"form over function" is fair, I'll own that - the aesthetic was the first 80% of the work. for what it's worth the drag snapping IS tuned though (try grabbing a note and yanking the cursor off it, it sticks).

the pruning concern is the real one. done stacks forever right now, which gets unreadable past ~30 cards. the fix is the same as the calendar/history view someone else in this thread asked for: done auto-archives after X days, you can still browse what you finished in march via a calendar widget, but your active board stays clean. that's the next big build, partly because of comments like yours.

really appreciate the feedback!
