A comprehensive feedback list

Why would you want to create multiple characters at once?
To kind of reserve names for example

The “assign one of your skills to LMB” does reset whenever you change zones, but the other options (move only & destroy destructibles) work fine.

It does, but it doesn’t fully cover the functionality I imagine many would like in their left click behaviour.

When multiplayer is released there will be an option to play offline, so there will need to be a screen where you select offline or MP.

Good point

It looks decent for a tooltip, but not the kind of comprehensive data that I’d like to see .

An advanced option for the data you’d like to see would indeed be nice, though I wouldn’t show it by default. I added a +1 to your idea though.
