HotKeys für verschiedene Zeichnungen desselben Typs

As a complement to this proposal, I request a panel that we can populate with our own drawing tools. Each of these tools should be editable in the usual way according to the current property settings (globally visible, color, text, line thickness, etc.), along with the ability to edit the color of the tile. Additionally, we should be able to decide in which order and where our own tiles are displayed.
