Ruby jEdit Plugin

I've been a big fan of jEdit for quite a few years now and I just downloaded a new plugin that I just simply felt compelled to write about, the jEdit Ruby Plugin. It's not the simplest thing to install but the integrated code completion and documentation features (including Ruby on Rails) are quite good. For example, when I'm editing a model object I can type in "has", hit ctrl-space and get a popup with the options "has_one", "has_and_belongs_to_many", and "has_many" options, and if I'm displaying the Ruby Docs window (currently docked to the right side of my jEdit window), it will display the documentation for each option as I select each one. Very nice. Perhaps some competition for RadRails?
