It is exists some tweaks to navigate from browser right to the problem file when you are using TextMate. I think this feature may be easily added to Ruby plugin Rails support. Here is RAILS plugin used for TextMate http://blog.inquirylabs.com/2006/09/28/textmate-footnotes-v16-released/ It may be easily added somewhere in plugin development SVN. Here is steps which should IDEA plugin should repeat http://ruy.ca/posts/3-Handling-txmt-URLs-in-Windows- Regarding to opening in Idea there a at least couple of implementation of such functionality already. One as TeamCity in browser navigate to source in IDEA, and second is well know XML-RPC approach. All together it will be big improvement. Thank you in advance, Dmitry
