On every widget it is possible to add a tooltip, to add extra information or only show an icon with the title in the tooltip.
But the only place where it is not possible is in the project navigation and menu documents for menu items. This would be very helpful as I sometimes only want to show an icon and don’t want to build a custom menu.
Looks like this will be in 8.12 See release notes
We have made it possible to specify an alternative text for menu item icons. That can be useful when you use a menu without text and want to keep it accessible to screen readers. (Ticket 100209)
That would be nice, I stumbled on this constraint a couple of times
