To add on to this idea a bit: It would be nice to have a general "ignore list". Similar to the way you can define files to ignore in SVN or Git. This way when downloading a folder I could have it ignore files I don't need. For example:
.*
logs/*
*.jpg
*.psd
*.gif

and so on...

Wow, that's actually a pretty cool theme! I'll have to port that into TextMate.

General themeing would be nice for Textastic, too :)

I can't believe this doesn't have more votes! I love the app and I look forward to future features but regex is my number one.
