• copying objects copies their animations and interactions, including "on click" or links if copying multiple at once.
• replacing an object doesn't destroy it's animations, links, etc.
• ability to replace multimedia objects (images, sounds, etc.) from clipboard, not only storage.
• ability to edit animations in bulk in more than just activation, type, and order. i.e. timing, sound effects
• animation rules such as reset on completion or not to actually do what they say.
• transparency to not block interaction with objects.

And this one is probably a faulty user error:

• change the default colours from that blue to something I'd occasionally use.
