I was presenting at the Eclipse Bangalore Camp last week. i talked about Mylyn at this presentation. i am user of mylyn for long, and totally love it.
Mylyn,an eclipse plugin is lying the foundation for the next generation IDE. i would say Task focussed IDE, is a fundamental shift in the way ppl are going to use eclipse.
I would recommended any one doing serious development in eclipse to look at mylyn. This can revolutionize the way you work !.
So friends, go and get plugged in ..
