Is there an error message in the Console app when you start Textastic?

That's how I plan to implement this: as an additional feature so that you can still work with Textastic as you are used to.

Actually, that's already possible. Have a look at the "Text" menu: Shift Left / Shift Right commands.

Selecting text and pressing Tab and Shift-Tab works, too.
