One of my favourite features

I want it as a screen-saver

*ahem*...rebuild? oops sorry. Well you'll be re-building 'til it's finised soooo.....
I'm sure you can see how useful that single GUI upgrade is.
Instead of manually re-building a massive non compressed texture-pack, UEd2 users can fix their oversight or "upgrade" an existing pack.
There is other functionality from UEd3 that I would not ask (never tried in UEd2 tho), but this is the single most common reason I need UEd3.
There is no stand-alone tool that can do it, and even 227 cannot (no one suggested it).
BTW the other "functionality" I have used with UEd3, is a little sneaky. I have used it, to map textures and shaders (not copy) to different packs. This makes them dependant on each-other, so people can't chop your stuff into a partial distro.
I have Never tried it with UEd2, but in theory it can work with any U content.
If doing this on purpose, rather than just to fix a missing item, you could protect an entire game. Every file depends on an item in the next, and so on.
Annoying as hell, but effective.
Anyway, getting side-tracked there.
Well done
