Doesn't work

How it works is this.

Have source file tab active. Type "> Diff:File" in command pallet and press enter. (This chooses the active tab as first DIFF file)
After pressing enter, it will show you a list of files to choose from as your 'Second DIFF' to compare against. (This chooses second DIFF file)

The second DIFF file has to be open before using command pallet in a non project setup. It will display the same error otherwise.
However it works as described by @soul4kills in a project setup (entire folder open).
