This is a script for Krita that lets you quickly switch between three brush "slots".

One of these slots has the eraser option permanently toggled on with the other have it toggled off.

Each slot remember the last brush it had and it also stores the size of the brush.

FORK EDIT: It adds a toggle-back feature when pressing the same shortcut key again, switching back to the previous slot instead.

To install this script, copy the contents of this repository to ~/.local/share/krita/
