Guild Member List Sorting

As a Guild leader I'm finding it very difficult ((well, impossible almost)) to manage my Guild now that the Guild Member List cannot be sorted by activity/inactivity or Guild Quest completion. I don't even know what is the sorting criterion at the moment.. Could we please have the former sorting options as before?
> Sorting by Names, by Levels, by Ranks, by activiy, by Guild Quest, pleeeease :)
Thx a lot.

Member List is default sorted by Leader, Successor, Join-date

Yep, figured it out, thx :)
Still, I want some sorting options ^^

Sorting is not possible throughout the game, ex guild list, mail and trade office.
