First off, thanks for a great piece of software.  And thanks as well for the amazing support you give it with responding to feature requests and user issues.

My current workflow is a lot like tu11ym0n.  TextMate for most editing, BBEdit for diff'ing.  What would be really handy for me would be a key command for "Edit in secondary editor..." (Cmd-Shift-E maybe?).  You'd probably also need to extend the preferences to allow a secondary editor to be defined.  Something like this would save me a lot of time, since I'm constantly navigating my way down to BBEdit in the "Edit with..." contextual menu.

Thanks.
