Very cool. I thought Nano would perform much better..?
A problem with some fast editors might be ease of use. For instance, I would have loved to try out JOE editor, but I couldn't find builds, the code is hosted on Sourceforge, etc. etc.
I think a huge feature for an editor is usability: is there a website where I can download a build for my OS? Does it update by itself? Is it easy to configure, install plugins, etc.?
