I love the new clickable stack trace in the clipboard and the debugger. The debugger is fantastic in general. However, I'd love it if the code in my project was somehow more prominent in that stack trace. My 1 or 2 lines tends to get lost in the 50 lines of /usr/local/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/active_record/ lines.
This isn't a problem in IntelliJ as the JDK and any jar's that I don't explicitly link to source would show as unclickable in the stack trace.
This product is awesome. Keep up the good work.
