This one is self-explanatory. Can likely just replace the fontstrings with editboxes and do a little bit of magic to get it working in a sane manner.

Probably gonna punt this one down the road, because it's gonna require quite a bit of rebuilding to make it work. I plan on rebuilding the UI eventually anyways.
