—, This really is quite simple to work around. A day's worth of work to implement something isn't really that important as a basic engine feature.
Though, making an expandable UI, that'd be an interesting way to go about that kind of issue. I doubt we will be seeing that with C3, but clearly there are a LOT of things that can be changed about C2 that probably will be. I'm sure it will be quite different.
TRMG, That's alright. Construct 2 was made for that kind of purpose. What you're asking for is pretty commonly done easily in programming (well, not usually done, but easily done), it's just a matter of knowing how. Programming knowledge DOES go a long way with Construct 2, so I'd recommend you look into programming after you've finished your game or something. It really helps.
