I understand the request but for tiny menus this might be annoying to wait until the items appear.
Personally I like the absence of a delay very much which could change when I go using bigger menus.
So maybe a configuration option for each menu node would be a good idea.
( ) Flyout-delay in ms: ______
( ) Click to fly out
That way we'd have configurable Flyout-times (0ms would be "no delay") and the click as alternative.
[Happy new year, by the way. Keep up your good work, mouser!
