I've been content with the Janus[1] extensions for about a year now but I just added MiniBufExplorer and I'm really enjoying that.
I typically keep three panes open, one of which is NERDTree. Right now my biggest gripe is the strange highlighting of the Play! framework's template files. The files are name.scala.html which results in weird highlighting of the inline Scala. I have yet to find a good solution (admittedly I haven't looked in a while) to this but if someone knows of one I'd love to hear it.
