I should note that I’m starting to consider this to be a design issue – while the two-window IDE+sbt experience is not terrible, it’s notably the clunkiest part of things. When I talk about putting more resources into improving Scala-IDE, this would be my top priority: figuring out a better-integrated experience that smooths some of these pain points. I suspect there are about half a dozen enhancements that would make a world of difference.
(I wouldn’t mind discussing those, but I suspect this conversation isn’t really appropriate here, and belongs on the Scala-IDE mailing list or some such. Anybody know if the project has a Gitter?)
