Komodo Side-By-Side Diffs
Provides the ability to use side-by-side diffs inside of Komodo. You get to choose which diff style you want on demand (contextual or side by side), simply choose the style you want inside of the Komodo diff dialog.
You can use Komodo's "Tools > Add-ons" dialog to install the add-on, since the add-on is published on the Komodo community extension list: http://community.activestate.com/xpi/side-side-diff
