This would be a good feature.
I will be using MVC Razor highlighting in the near future, that comes in at least 2 flavors c# and vb.net with maybe more to come after.
If I could define a new syntax definition file and submit that it would save you having to deal with every new language flavor that appears, plus allow some seriously customable color schemes for existing syntax.
WebDav client support would make Textastic more usable and enable SVN versioning.
Perfect for me.
I need c# specific keys like (){}[]"':;-_'|&
If the shift key could be used to double use the extra row ... ?
My ideal extra row would be:
SHIFTED {}<>:"_+&|
NORMAL []();'-=/\
And the TAB key to the left.
I would love a cursor cluster, left, right, up, down.

Love the App.
