Hiding UI

[Titibello]

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?
