Status Menu Bar

The Status Menu on the Lowest Bar of the Unreal UI is divinded into two areas; SCC integration and Universal Constraint Settings for Grid, Snap, Rotation, and DrawScale

SCC Controls
SCC, Source Code Control, is now integrated into Unreal and supports ( presumably ) any SCC program, though only Perforce and Alienbrain seem to have native support  ( as of 6/19/2010 ).  SVN, CRCS, VS users will need to code support themselves.
