If I check and double check I can figure it out, but it's often not clear if the Red or Green button does what action...like delete a topic when pruning, etc.

Really? I was trying to make them sort of internationally understood. Red meaning no, off, stop etc. Green yes, on, go etc.
No?

At my first glance... the colors made perfect since. I think better then checks and X's as they can mean the same thing.

Just my 2 cents 🙂

I like the green and red, but some hover or explanation just to be clear would be nice....not crucial.
