Playing around with the cursor following the curvature of the window exactly. Instead of the 90 degree cursor macOS supports by default. Quite interesting how natural and smooth it feels.
@mathijskadijk That’s really nice and smooth, though I do question the utility. The distinct horizontal, vertical, and diagonal cursors help signal which axis (or axes) you can drag.
Maybe a middle ground: instead of mapping directly to the curve, animate the cursor when transitioning between one-axis and two-axis drag, then back again?
