Editor: Undo button visible left of the color palette

[neoneye]

Problem

On desktop with big display, the undo button is shown in the bottom bar.

However on the iPad there is no undo button in the bottom bar. Despite being plenty of room for it.

Currently the user have to open the tool: paint menu, to get to the undo button.

When I see new user use the editor, they don't realize that the there is an undo button.

Solution

Show the undo button next to the palette.

Maybe eliminate the redo button.
