Customization bugs

[Ingolf]

While I remember - please ask, @VectorStyler.

More will come

• Renaming items is often not saved unless an action or folder has been added/removed
• macOS at least - deleting custom toolboxes doesn't work
• In many instances placing something as the last item puts it in the subfolder below or something else, I have to put whatever in the second to last position and move it down using the buttons.

@Ingolf Added these to the backlog.

@Ingolf These issues should be fixed in build 1.1.062
