Feature request: Sort functions by visibility/override modifiers.

[carstenhag]

Hello there, thanks for developing this plugin. Tried to use it, but it seems like only basic things get sorted.

I would like to have overridden fun at the top, then public and at the bottom private ones. Currently, I can't do that :(

Your idea is good, but I'm too busy to study it recently. Maybe I'll add that in the future.
