I use "Textpad" and I love it.
Lets you do a lot of little things that save a LOT of time.
Like:
-set colors to key words (any color you like)
-paste stuff as a block (instead of lines)
-make changes to a GROUP of files (like replace all, but to 50 files at once)
-show line-numbers and spaces

many other helpful things as well.
