We can use the right-mouse-click context menu on a toolbar to toggle the visibility of items, via the "Visible Items" menu. However, at the moment, these toggles make the menu disappear, so that you have to move your mouse to the toolbar again, right click, navigate to the Visible Buttons submenu, then navigate along it (and it's a long menu) while keeping both menus open. That's a lot of work if you want to toggle multiple items... I suggest changing the behavior so that toggling items in Visible Buttons submenu would keep the menu open, so that the user would need to leave it in the direction of the context menu, or press Esc, or click somewhere, to close it. Detriment: Breaks typical menu toggle behavior
-1 to change standard behavior (a context menu closes on click), less strongly objecting the use case (complex interaction with items, requiring a different UI). The point of this menu is to change one item, it's not meant for a full-fledged customization. We have a dialog for this purpose. => NAB/WF
The 'Customize Toolbar...' launch of the full dialog is simply the better way to adjust *multiple items* on a TB (or other UI component)--it already includes all the check-box selections for button actions as assigned (or previously customized) and available to select on the 'Visible buttons' context sub-menu. Making multiple-selections from the 'Visible buttons' menu would be at odds with all other menu selection actions--that apply immediately and close the menu. And would require some awkward UI, <Esc> or <Apply>,<OK> to then exit the sub-menu. So see no real advantage to changing behavior and making the sub-menu stateful for multiple picks. -1 and => WF
Some disagreement to the idea, resolving as NAB.
