What I mean is, if I'm in the enemy menu, but decide I need a wall there, I'd have to go up all the Way, then down all the way through the Wall radials. With a full palette on the side, I'd just have to click on the Wall. This isn't really noticeable with how little there is, but if you have a lot, it could easily become a lot. Like, going up from fireslime to slimes>smallenemies>enemies>actors>entities>root>>statics>walls>dungeons>broken>brokenWallTypeA. or something like that.
Other then that, its really just Work in Progress stuff I think.
