What inspired this wish list request? I have a lot of toolbars and organizing and editing them can become challenging.
What is the improvement you would like to see? I would like to see that if you right click on a toolbar icon you can go right to its edit screen. I would also like to see that when you hover over the three dots on a toolbar "grouping" and the directional arrow pops up that the name of the toolbar grouping would show (this would make it easier to know which icons are in what group vs having to interrogate the toolbar list menu).
Why is this idea important? Toolbars are an amazing efficiency gain but once you start to get more than a few going the Maintenance of them becomes an efficiency drag.
