So I just realised that I am going to run into this issue since I am adding quite a few server groups to my server, but here it is.

If I remember correctly, when you add more server groups than your screen height can handle in one list, the server groups dropdown will be given a small arrow at the top and bottom so that you can scroll up and down.

I suggest the dialog grows in size horizontally, to 2 or 3 columns and then scrolls right and left a column at a time, instead of up and down, one result at a time.

I have attached an image and here comes my;

TL;DR: if menu B is the height of A (because loads of groups) then make Menu B double over (2 or more columns) as shown in C
