Feature: Rotate left button

[davidak]

Problem

I want to rotate the image left. I have to click 3 times on rotate right to get it.

Proposal

Add a button left to rotate right.

Prior Art (Optional)

Apples Preview app has a rotate left button that turns into rotate right when holding the option key.

I found out by trying that holding the STRG key changes the rotate right button into rotate left. I do have a lot of free space for more buttons. Maybe add it when there is space and keep this option key behavior when there is not a lot of space, like on mobile devices screens.

Something to keep in mind for the future rewrite, for sure. In the meantime, you can hold Ctrl and click the rotate button to rotate it left.
