I installed and got acquainted with Mylyn today. I also watched the excellent Mylyn/Tasktop webcast.
It's obvious how you can add individual packages, classes, interfaces, methods, etc. to a task's context in Java... but what about when using JavaScript or Python? How about HTML/CSS/JSP pages? Could Mylyn somehow add only certain JavaScript functions or objects to the current context? (other than the option to add the files themselves to the current context). The webcast mentioned the DLTK plugin works with Mylyn and supports dynamic languages briefly but not much more that that.
