Yeah, I noticed that later on. I was just about to compose a feature request email, but I guess I don't have to!
The quick custom condition is /alright/, though there are a couple problems I have with it; I would prefer to be able to assign it its own name and icon do differentiate between different effects. Even better, I'd also like to be able to modify the conditions list outside of combat. I spend enough time in prep that setting them up then would be convenient, while also saving me some time during the game. It would also allow me to re-use the same condition over the course of a battle, which I'd imagine the current setup can't do (especially if there are multiple "special" effects in the encounter).
And thanks for looking into alternate themes. The current one is actually one of the things that's kept me away from this app for so long; I just find it so difficult to work in.
(edit: Noticed quick conditions was the potential feature you were talking about, while I was talking about the existing custom conditions feature)
