Sharing toolbar autosave on close issue

Hi guys, I have a problem with toolbars automatically being saved upon closing Rhino with NO warning.

We share a toolbar that I often update and SAVE manually, but if my colleague has his Rhino open and closes it after I have saved the toolbar changes and closes my Rhino, then his Rhino automatically writes over the toolbar file with no warning!

This is annoying so could you add a ask to save IF changes are noticed?

I wonder if you can put the toolbar in a folder with user rights of some sort, then give your colleague only “read” rights to the items in the folder and yourself “read and write”…?
