Do you mean you want another vertical hotbar, or just that you want the buttons on hotbar 4 on the vertical bar?
Adding another vertical bar can be done, but will just take some time. If it's just swopping buttons around, did you know you can load & save hotkey sets and move the whole lot at once?
I don't know what's different about the combine server so the bank thing will be difficult for me to fix. Can you have a look at the individual bank mods on the site to see if any are suitable. The bank window is completely independant of everything else and originally came from this site so downloading an alternative should be a piece of cake
If you can't find any big banks that work on that server, let me know and attach your UIerrors.txt file and I'll see if I can get it working for you.
