Well guys.... I've had quite a few requests for this, so here it is.
I have now included the Short Duration Buffs window with my old version 2.0 of my Buff window.
At 1280x1024, both of these buff boxes fit across the top of the screen, with a little room to spare.
At a lower res, you may need to move them around a bit to get them where you like...
This is a very simple install if you already use my version 2.0. In the zip file, there is one file called EQUI_ShortDurationBuffWindow.xml. Simply copy this file into your CUSTOM UI folder and you're all set!
