Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Log version at startup, add copyright verbiage, etc.. Move log init into the top level and pass it around (dunno why global doesn't do what I want tho..) Change hysteresis temperature to 1 degree.
