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!
I'll definitely consider adding support for Groovy. I always wanted to try the language :)
I see. Thanks for clarifying.
What happens when you switch to the normal JavaScript syntax highlighting in the File Information popover? What is the file extension for UnityScript?
Hello, I'm not sure what you mean when you say that "when dealing with slow links what it does is a wait save check cycle that can last 10 minutes". When I edit files in Textastic I never notice when the file is saved in the background.

Can you please tell me what you are trying to do and what "slow links" are meant to be?
Sehr gern. Danke fürs Feedback!
Well, I probably made the screenshot with the German keyboard enabled. The German keyboard is QWERTZ instead of the US QWERTY.
