Viewing comments in the history panel is pretty painful.
-It's not possible to view an entire comment for the history of a Folder
-Double clicking on a history entry for a folder makes the program not know what to open (should this open in explorer or a diff tool?)
-Double clicking should ALWAYS "Diff Changeset". This is likely more common then opening up a temp file with that particular revision.
-Long comments should have tooltips with the Entire comment (really all panels should have this feature)
