I am a huge fan of the Sublime Text Editor. Today, Greg Clarke and I created our first plugin. It will add items to the Tab Context menu that will sort the open files, by file name. Sublime is a really fun environment in which to program in Python. You can download the plugin, copy it to your Sublime Text Installed Packages Folder, rename it as TabOrdering.sublime-package and it will be available to you once you restart Sublime. To create your own plugin see NetTuts' instructions.
