Rotate objects separately
If we make a selection of objects, and then rotate it with a corner marker of the bounding box (or with the Rotate tool), they get rotated all at once, as a single object.
If we want to rotate all separate objects in the selection separately, the only way to do it is with the Transform Each dialog, with Preview option on, with arrow keys, changing the Angle value. Doable, but not fun.
What if we get a mode, at least for the Rotate tool (since it’s a special tool for rotating), let’s say, with Ctrl/Cmd held, to rotate object separately?
Don’t say 'Cmd/Ctrl is taken to temporarily enable a selection tool' — no. It’s taken only before you make a click, and not during the drag, when the mouse key is already down.
