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.
Please add any features (like custom style sheets for preview) you would like to see.

I'd like to know how you use Markdown in your workflow.
I tried to implement this but there were some problems:

The gestures interfered with scrolling and zooming: if you just slightly changed the distance of your fingers, the scroll view would interpret the gesture as a pinch-to-zoom-gesture. You also had to place the fingers for swipe gestures on the screen at exactly the same time or it would be interpreted as scrolling.

So, I had to remove this feature again because it really wasn't usable. I also found those gestures to be quite slow compared to a tap on a button.
I've added some more keys to the row above the standard keyboard in Textastic 2.1. Notably, the "=" character was missing for HTML editing. You can now scroll this row horizontally.

I'm considering to make this configurable in a future update.
