I am concerned that I might accidently click the "Clear Bookmarks" button and then undo a lot of time I spent creating bookmarks in many different important places in the project, that I would be totally unable to remember where they all were if they were deleted.
Since "clear bookmarks" is somewhat related to the "remove all breakpoints" menu option in the "Edit" drop-down menu, it might be helpful to remove the "Clear Bookmarks" button from the toolbar so it can't be accidently clicked on, and instead add "Clear Bookmarks" in the "EDIT" drop-down menu.
