Add commands option disabled for View Toolbar
1 Answer

Mine is the same, but I don't know why and I don't know how to unlock it.
I noticed that there are a few other toolbars that behave similarly - so my guess is they don't want you to change those toolbars.
I also noticed that it won't let me drag&drop a command into the view toolbar, although I can drag&drop with most of the other toolbars.
