As per Karl’s request, I added the ability to upload files to codepaste and to download code files from it. They were actually easy features to add (it only took about 50 minutes). Hopefully they’ll be useful.
More importantly, I got a chance to look at the code I’d written for it. It was actually pretty nice – I was surprised. I had completely forgotten about that theme/skin system it uses. It made it simple to add the additional html to the interface, and to style it for the two skins.
