xPanels allows you to create rectangular panels in all different colors, alphas and funky textures for your UI.

Slash config:
/xpanels to open the GUI

Dependencies:
This Addon uses LibSlash for slash commands.

A note about overlapping frames
WAR features 5 different "layers" in which frames can be created. The lowest is the Background Layer, which is where xPanels are located. It's not very controllable however, in what order frames in the Background Layer are arranged - I will add a possibility for xPanels, but if the Panels overlap other addons' frames, there is not much I can do about it. If you think that a frame of another addon shouldn't be layered to background (and overlayed by xPanels), please contact the mod's author.

How to use your own textures
xPanels 2.0 gives you the possibility to include your own textures in the game. To accomplish that, install the Custom Texture Package (unpack either in your /AddOns or /AddOns/xPanel-Folder) and follow the instructions in the readme.
I will probably add own textures in the xPanels Core at some time.
