Feature request - sorting and arranging columns in characters screen

[thegilm]

Hello!

A quick feature request as the title says - it would be very nice if the columns of the characters overview would be sortable.
Possible use cases: sort by actively training/not training, sort by location

Also I'd consider it useful, if the order of the columns could be rearranged, so I could see the the information that's relevant for me first and scroll for the less important stuff.

Hope that makes sense.
