Hiding UI
 

Is there anyway to hide original Rift UI when u get a new unitframe, hud or buff addon? For example I downloaded Myui ( http://www.riftui.com/downloads/info126-myUI.html#info ) which looks like a kickass addon. But instead of "replacing" Rift ui it just adds the addon without removing Rift ui. So i end up with tons of raidframes buff bars etc.

Is there any fix for this or do i simply have to have Rift Ui draged into corners etc?

If you go into "Edit Layout" you can disable each frame. Click on the frame you want then uncheck the "enabled" box.
