It would be really great, if Ansys APDL language would be supported. You can get an example from Notepad++ or VIM (sadly no fraise file). Thank you for your great app and for considering it.

Currently, Textastic always displays the tab character as a gray triangle. It should be possible to disable this in the app's settings.

Add the ability to have a vertical column marker.  It can be set to any column or use a default of 80 characters.

I would be very appreciative if you could post an update with true retina display support. The app seems great, but there are a few things that are blurry, including the source text itself, regardless of which font I select.

Thanks for a great app, I plan to use it often!

You should be able to open a file as read-only.

My iPad would completly replace my laptop, if Textastic had better support for hardware keyboard.. (iPad keyboard and bluetooth keyboard)

Keyboard shortcuts for saving, preview etc.

Add actionscript suppourt please I really need it :(

Currently it looks like you can update files on the device from their source one by one.  Something to help ease the absence of SVN and other version control solutions might be found in allowing full directory structures to be updated as well as single files.
