Yes, SFTP support is implemented in Textastic 2.1 and is in review.

You can vote for VGA support at http://feedback.textasticapp.com/feedback/7897-external-monitor-vga-out/ – I plan to implement this in a future update.

Thanks for your feedback!
Would it be possible to give me access to the FTP server so I can try to reproduce the issue? If yes, please send me an email.

Another possibility would be to wait for Textastic 2.1. This version is currently in review at Apple and I fixed some FTP issues there.

It could be a problem with character encoding – there is an option for character encoding for FTP connection in version 2.1 – Textastic 2.0 always uses UTF-8. Are there any files with unusual characters in the folder?

I also added a feature in 2.1 that allows you to write a debug log so I will be able to find out more by having a look at the log file.
I could certainly show a list of recently opened files in a Popover when tapping on the file name label. Also, a close button would fit nicely in there.

My problem really was how to implement this without wasting space – that's why I didn't want to have tabs (as in browsers like Firefox). I agree that this would really be a great solution.
It's implemented in Textastic 2.1 which is currently in review at Apple. See http://feedback.textasticapp.com/feedback/22877-whats-new-in-textastic-21/
Thanks! I'll try to find the cause for this behaviour.
Thanks, I'll consider it. I implemented it this way because that's how Apple's Mail implements the move command. But of course you're likely to have more file system folders than mail folders.
Can you please tell me the steps I need to follow to reproduce the problem? Unfortunately, I use Subversion myself so I'm not familiar with Git, sorry.
Textastic 2.1 is currently in review at Apple.

New Features:
• SFTP (SSH connection) support with user/password and public key authentication
• FTPS (FTP over SSL) support
• New settings for FTP: connection mode (active or passive) and encoding
• More keys in the additional row above the standard keyboard (the row is now scrollable)

Fixed:
• Fixed some auto-correction bugs
• Fixed issues with international keyboards
• There was a crash when trying to open the WebDAV screen while not on a wifi network

Thanks to your feedback, this version also fixes some other minor issues.
