Just the other day, I was thinking, and decided to customize my version of Notepad++ a bit, making it better for glest's lua. Syntax highlighting recognizes ALL of glest's lua functions, allowing for easy detection of simple mistakes, such as misspelling. It also boasts an auto-suggest (CTRL+Space) for all lua functions. While small changes, they are noticable, and the file is easy to load. For windows, just run the program. The first page just has you select your NPP directory, where the default is fine for windows, though other OS's may have to change. It takes less than a second to do, and does not affect your working NPP.
It is multi-platform, and should work with everything NPP supports. However, the program to execute this is a win32 app, so an emulator is needed. I actually made a Linux version, but it's the same filesize, so didn't upload. Sorry. If enough request it, I'll take the time.
