Things I want in my IDE:
- monitoring/alerting (how many times is this method executed, how long does it take, how many errors, etc)
- discussions as in Google Docs on code fragments, rather than "comments" that are part of the git history (comments are an orthogonal concern from checked in code)
- visual representation of my code base
- ultra fast automated test that cover only what I recently changed
- a documentation system that makes sense
