What is it?
NDragIt allows you to grab onto a frame and move it around. When the frame is closed, it is reset back to its original position.
What frames can I move?
All of the standard UI frames are now draggable, such as: Character, Spellbook, Trade, Social, Mail, Auction, Battlefield Score, Quest, Loot, Trade, Merchant, Stable, Guild Bank
In addition, a couple of annoying addons are now draggable: Ludwig, Lootlink, DBM
How do I configure it?
NDragIt is configured via the Rock options menu. You can bring that up with the slash command: /ndi or /ndragit or /dragit.
But I want to drag a frame not listed!
In order to make a frame draggable, you need to know its name. The console command /nfi will show the name of the frame under the mouse cursor.
Note the frame's name, then add it via Add in the Rock options menu.
What are the caveats?
There are some frames that don't really suit NDragIt, such as the bag frames, and inherently draggable frames like the battlefield minimap.
I suggest you play around with adding different frames; if it all goes wrong, you can always reset everything back to "factory defaults" via Profile->Reset Profile in the Rock options menu.
