Make resizing feel familiar.
Corner-only resizing and visible square handles did not match the interaction I wanted. I requested resizing from every edge and corner, with the cursor showing what would happen before a drag.
ITERATION
Invisible edge targets, directional cursors and an optional Alt-drag shortcut. Notes expand to show their text instead of creating a second scrolling area.
TRADEOFF TO TEST
Less visual clutter can also make resizing harder to discover. The next test should reveal whether the cursor feedback is enough.
