New editor for Rails

New to me that is, it's been around for years. More random browsing yesterday sent me in the direction of a handy blog post describing how best to set up jEdit for efficient use with Ruby and/or Rails. Following his advice and downloading most of the suggested plugins, it seems jEdit might indeed be a nifty editor for Ruby/Rails. It adds some features that RadRails is missing (for now), though it does lack one or two nice things that RadRails has. Two of the key reasons I can see myself using jEdit for a while instead of RadRails are:

• Window splitting/cloning - this was probably my most appreciated feature in the Zend IDE for PHP. Being able to split files into two views of the same file in the same workspace is invaluable when working on long files where you need to constantly jump between code at the top and bottom of the file, or where you need to work on two or more files at the same time (e.g. Raisl controller, models and views). The splitting/unsplitting isn't quite as easy as in Zend (took me a while to find the tiny arrows for hiding a split frame/window), but it's much better than not being able to do it at all.
• Colour preferences - I have a feeling I'm just missing something here with RadRails and I'll be honest, I haven't bothered looking too hard. I like to have a black background to my text editor and then appropriately colour the various keywords. I can't find a way to do it in RadRails, but jEdit and Zend both let me.

I'd like to think I'll go back to RadRails at a later date though, as it has Rails-specific things like the Servers tab for quickly starting a local Webrick server and the Generators tab for getting even more lazy so you don't have to get into a console, find the right directory and then type out the commands to generate scaffolds and the like. I might start using jEdit for PHP as well, though I'll see how it goes. The only real reason I'm contemplating this is that my Zend support just ran out and there's no way I can afford a few hundred dollars to renew it. That would be fine, but it seems the latest version of Zend I have installed (5.1) runs painfully slower than the previous version. Even on my dual-core Athlon64 at home with 2GB of RAM, Zend is now running very slowly (pauses between typing characters and them appearing on screen, etc.).
