allow Add Control button to be turned on & off
This would save time having to click it for each control added to a course.

The same requirement applies to adding multiple "forbidden route" symbols
the shortcut doesn't work for me running PP on a Mac through Virtualbox so it would be useful if the button could be double clicked to keep it on (same goes for other buttons)

CTRL+A is a workaround, but locking the Add Control mode would be really appreciated.

You can just press Control A with your left hand and keep your right hand on the mouse to click the control to add.
