I would certainly like to see an updated armor-crafting system (appearance), much like the updated dummy color system we have in the OOC areas.
To be more specific, as a temporary solution perhaps, I'd like to see an "outfit save slot" system. Basically it would work the same way as regular crafting, but when you're all paid and done you get an option to save it to an appearance slot in your OOC menu. Maybe make five or so of these slots. It's not that big of a hassle, but this is more of a quality of life suggestion. If you pay for the dyes, and the expensive alteration, I think it's more than fair to keep the appearance locked into one of your save slots you can switch to for a small fee, or freely.
If your disguise or outfit goes out of date or you want to change it, you simply make the necessary payments and changes again through the crafting menu and overwrite the save slot of that outfit. Of course, you can only change into the "outfit" of the same type of armor. So if you have, let's say, some type of cloth you have two appearances for, you can only change into either appearance with the same cloth/armor. Crossing Armor Class types won't work, of course, so it keeps the system mostly free of cheesing. Also helps eliminate the need to carry a million different pieces of cloth/armor to switch out of, if your character is like that.
I shot this idea up pretty quickly and haven't given it too much thought, but maybe this would be a useful addition.
