HideParty allows a user to hide various parts of the default WoW user interface.
Since I wanted to hide the ugly blizz party frame, this addon was perfect, except it also hid the player and target frames,
so I've taken v1.0, because of it's simple code, and modified it a bit, so it now hides only party and raid frames.
Download my modded version: Google Drive
Original main page of the addon: HideParty
Credits to the author(s), ofcourse, I just deleted a couple of functions from the original code.
You can always open the .lua file with any text editing software and see what's there. You can even modify it yourself if you want.
Hope someone found this little mod useful.
