This is awesome. I'd love if the developer would add (even if it were optional) Command+[ / Command+] functionality to indent multiple lines at a time.
multiple lines indentation at a time is supported. You have to select multiple lines and press tab (to indent) or shift+tab (to remove indentation).
I like the fact that if you select multiple lines with one line partially selected, it works as expected (selecting whole of the partially selected line)
If you have a block of code/text selected, Cmd+[ and Cmd+] shift the entire textblock one tabindent to the left or right, maintaining the relative indent level of each individual line.
Is it different from ctrl+tab / ctrl+shift+tab ? Because these shortcuts works in this editor ("Multi-line highlighted text is also tab-able, and shift-tab removes a tab character instead").
