I make heavy use of the Changes tab in IDEA as I'm the one doing code
review in my team.
Unfortunately I work on a distant SVN server. That means each time I
double-click on a file in a revision I get the dialog Getting Revision
Content blocking my actions for a few seconds.
It'd come handy to be able to get this done in background, so as to be
able to work on some other matters when getting the revision takes time.
