Awesome! Thanks, linkman! Will try to make a nice simple example as well.
I think it has turned out great - nice, simple, quick to use. Will have to play around a little, check it out more. Try layering it, stuff like that (like pulse a little and get smaller over time).
One little thing - in Actions there are two links to "Scale over time" - one has almost all settings, the other only settings for interpolation. Is there a limit to how many settings can appear in one link or it just ended up there?
Evil edit: Ok, just tried layering the effect, but it always takes the first behavior. Would be actually be possible to layer them? Because that would allow for even more crazy stuff - like set one to Scale down to 1% over 5 seconds, other to pulse every 100ms, etc. Well, if it's not too much work. This is super great already.
Extra evil edit: Also... Would it be possible to work off off the current size instead of the base image size? So you could, say, set the size to 400% and then start a behavior to scale it down to 1%? That would be really handy.
