[Suggestion][Flexitoolkit] Features for easier handling of largelevel rank lists

[IchoTolot]

While replacing every level of Reunion today some things came to my mind which would make such tasks a lot easier:

- The Flexi toolkit window should be able to be dragged larger, so you can see all levels in a rank at once. ---> No more tedious scrolling nessesary!

- Also when replacing it takes you to the top of the list again --- not fun when replacing the lower listed ones.  ---> When replacing a level the list should stay at that entry, as it is mostly the case that you want to stay at that area of the list.

This part is a bug.

The bug is fixed for the next update. Still need to figure out how to best address making more levels visible (or whether it's worthwhile to do at this stage at all).
