Adds "quick tooltips" to quickly see the name of a tab in the Properties
editor. (See patch for visuals.)
From own experience users are often confused about the name of the different
tabs, and I always found the delay to see it in the tooltip annoying. These
quick tooltips have been introduced for the toolshelf and solve this issue
nicely here. There is still a delay so that simple mouse movements won't
trigger the tooltips, but they show up a lot faster than normal tooltips now.
This may have the side-effect that icon only enum-item buttons will show the
enum name when there is no RNA property description. Previously we wouldn't
show this, even if available.
