Now that we are adding more pie menus, we could make some small but effective improvements to them.
First, the wedge could be highlighted as you rollover it, to make it clearer how big the area is, like so:
==Active Item highlighting
Currently, we have an indicator for activated options for pie menus, but it is so subtle that you almost can't see it:
This is inactive:
This is active:
Even if you know it, you have to look very closely using a loupe to see the difference.
We can make this vastly more clear, like so:
The blue color is consistent with the way we display active elements in Blender.
We can then distinguish between active and selected as demonstrated.
There's a slight quirk in the way we handle input: Normally, if you hold a key to invoke a pie menu and then let go, the pie menu is dismissed. This works if you move your cursor to an item, or to an empty area. But, if you don't move the cursor at all, this doesn't work. This makes the behaviour inconsistent, and makes the pies 'stick' in an annoying way if you regret opening one.
There's a bug which sometimes prevents some pie items of being highlighted correctly, making them not as reliable as they should be.
These three changes should make pie menus more delightful to use.
