Is it possible to launch the diff tool through command line? I'm wondering because I would love to use it as an external diff/mergetool for example from Mercurial, etc.
Also, I often need to compare directories. I've seen there's an IntelliJ to compare directories, but usually the directories I need to compare are not within an IntelliJ project, so I'm not sure this plugin would work. It would be great if some of these tools were available outside IntelliJ via a shell extension, from the explorer!
