I would love to see ruby syntax highlighting included+ Dropbox/iDisk sync

Ruby syntax highlighting is actually included in the app. Didn't it work with your files?

There is already a discussion about Dropbox support at http://feedback.textasticapp.com/feedback/7436-dropbox-support/

I've added your request for iDisk support to the entry about a WebDAV client: http://feedback.textasticapp.com/feedback/7780-webdav-client-idisk-support/

Oh, and please create a separate entry for each individual feature request in the future – thank you!
