Custom Tool Box Widget

An extremely useful tool would be a custom tool box widget that can be hotkeyed in and out when in fullscreen mode. Being able to drag and drop tools, buttons, and menu commands(applied to custom buttons) on the widget that are the only tools needed for particular workflows, increasing screen real estate automatically. Saving custom toolboxes as a separate file to be shared or archived for future or fresh Inkscape installs. This same feature can be found in Corel Painter and has been invaluable to the workflow: https://youtu.be/5GRCX9DHNGA?si=W-BHHq9A4R3ub7vN
