I click on the "Transform layer" button and then I'm lost: if I use a mouse to move fast, it's easy to move a picture vertically as well (accidentally).
Also, to stop precisely at 50% I have to magnify the screen, calculate what pixel 50% is at and then carefully move pixel-by-pixel
Likewise, the magnify/rotate should allow
So a few suggestions on how to make these operations more convenient:
- Make holding ⇧ constraint the direction (so you can only move ←→ or ↑↓)
- Allow moving by a specific value in pixels and % in a user defined direction
- Allow magnifying by a specific value in addition to dragging the circle on a line
- Allow rotating by a specific ° value in addition to dragging the circle on a line
- Add the common rotation values (0° ↷90° ↶90° ⤸180°) as extra buttons adjacent to the rotation line
