No, sorry, I'm using APIs that are only available in iOS 5. Due to changes in Core Animation it also makes testing a lot easier. I also have not found that iOS 5 slows down the first generation iPad.

It's possible using private APIs. I don't want to risk my app being rejected by Apple.

Textastic can load TextMate-compatible syntax definitions - this is described in the manual.

Unfortunately, there's no API for that. See http://feedback.textasticapp.com/topic/20131-better-hardware-keyboard-support/

Sounds like an interesting idea. I'll try it out when I have some time.

You should already be able to see them. For FTP connections, you need to enable the "Show hidden files" option in the FTP connection's settings. You can edit the connection's settings by tapping on the blue arrow on the right side of the connection.

I'm considering adding Multimarkdown preview support in the future.

Can you please have a look at the server log file? It should have an error message.

Thanks!
