I love your "Controller" link. It would also be great to have an "Action" link which opens TextMate with the current action selected.
Don't know if it's been added since you created this issue, but it looks like the controller link already goes directly to the action. The line number for the action is specified in the controller link.
So, this issue should be closed.
Alright, I'm closing this, if there is still an issue please comment and I'll reopen
