This is a small suggestion update to the flyout menus. Currently there is no way to know from the flyout what the contained items do unless you already selected them, which can carry an unwanted behavior, such as exploring the render flyout, align flyout, etc.
The current behavior:
Hold Click - Spawn menu - Release over an item to select it.
Suggested behavior:
Hold click - Spawn the flyout menu - release - keep the menu open so you can navigate over the items and see the tooltips, like any other tool outside of these menus - Click the desired tool to use.
It's 1 extra click that saves repeating the process, specially for newcomers to 3ds max.
