This is displayed when you go to the root directory in the Files section and choose "Help". It is shown at the bottom of the help screen.

This will be possible in Textastic 2.2 which is currently in review at Apple: tap-and-hold a file and select "Preview" – this also works for other file types like PDF or Word files.

Thanks, it's great to hear you like the app! :)

Thanks, I'll consider it. Chmod is also a command that's missing from the ftp client.

Currently, you have to download the files and upload them again to move them to a different folder on the server.

Adding custom syntax definitions will be added in Textastic 3.0.

If you use this website from your iPad, you have to tap once on the vote box and then once again on the arrow on the top of it to cast your vote. If you use it from a computer, you can simple hover over the vote box and click on the up arrow.

Thank you!

I plan to support this in Textastic 3.0.
