With multiclienting its not so good to switch between windows with ALT+TAB keys. So i tried to find anything to bind windows to make a hotkey for a champion, for healer, etc... So i made it. Its not best, but it works... Heres how to make it:
1. Download wrenamer.rar, unpack:
2.
Run all clients and start bot to find your characters. (*)
Run
wrenamer.exe
In first line write: "Battle of Immortals- (
Gemini: Realm
2 )" {dont miss spaces, its important. Change to your server and Realm}
In second line write: "1"
This will rename 1st window to "1", do it with all your windows, 1,2,3,4,5,6...
3. Donwload and Install
AutoHotKey program.
4. Donwload and unpack this script and edit it as you want:

You can change binds, for example: !2::WinActivate 2
!2 = its ALT+2, can change to ^2 = CTRL+2, ^y = CTRL+Y etc...
WinActivate
2 = "2" - your window name, you can change it to other name, to make it like: 1 - your tank, 2 - your healer, 3 - your magus, etc. I need it to use AOE's easier.
* You have to run bot before you rename windows, because bot will not find your character after that.
[-]
You have to restart bot, and rename windows after changing realms.
Looking for any better idea
