I recall reading that the options available for a given state in an interaction (currently Transitions, Width, Height, Opacity, Display, and Delay) are planned to be further built out, but I couldn't find the thread with that reference.
I'm this close to being able to use interactions for a lot of things that would require some js custom code instead. They're already awesome for simple things, but it didn't take long using them to bump up against the ceiling.
For example: For some menu/list hover operations, delays are really useful, and of course :hover doesn't supply that so the hover interaction starts to look like a godsend. But hover interactions don't let me restyle on hover the way I need to. It's nice that you can combine the two, but alas, the delay offsets the two sets of effects uncomfortably.
FWIW, the ones I seem to keep wanting that aren't there would include:
... pretty much the ones that affect the styling of the objects, as opposed to radical page position like Float and Clear, (which seem like they could be impractically complex and maybe less likely to be desired in the first place).
@thesergie - any insight into where more interaction options might be in priority?
Fantastic feature, guys - I'm really looking forward to using the afterburners when you bolt them on!
