QOL / UI - List Grouping & tree view Improvement

It is nice to be able to group blocks in the K menu and also on GPS, but afaik you can only group EXISTING items and then the group is fixed like that forever - it would be grea tto be able to ADD and REMOVE items just per drag n drop. Atm i need to delete the grouping and regroup. And obviously for GPS that is very dynamic, allso ships that are 'work in progress'. I think thats not too much effort to implement but would greatly enhance QOL of the UI! Thanks.

Even more so, sorting the list by personal priority. For example the cockpit block is kinda important if u want to add buttons to the action bar but if there are a lot of blocks in front of the alphabet u have to scroll down all the time. so sth like FAVORITEs or just custom ordering or some improvement would also be very nice.

when using the list/treeview for GPS and GRID controll, the sub groupings are nice, but every time i press K or just open/close the window i resets. often the first groups have many items andi dont wanna s the conttens. so often enough it would be beter to have the subgroups collapsed.

even more i think it would be nice if the UI would just remember which were collapsed and expaned and maybe even the scroll position.

if u dont wanna keep that data in memory at least some buttons for 'collapse-all' 'expand all'.
