For those who like working on the cfg "raw" in notepad, try notepad++ It is a free program. a lot of features, and you can open a lot of notepads simultaneously, and copy and paste between them. It also never "close" your cfg, and just by opening your notepad++, you access your cfg again.
Also have line numbers, for good referencing. Overall, it is just a notepad....but with a lot of features!
