Oh wow I need this and so far on my N9 it looks great and works pretty well.

A couple of things from my first test:
* the File Open selector wasn't sorted alphabetically at all so it was very hard to find the file I wanted.
* my Python script that I tried to open had no file extension which confused the selector which tried to open it as a directory.
* the helper bar needs a Tab character in it and I can't easily add one manually.
* the menu for File, View and so on appears on the landscape edge (left side running down the screen) when the phone is in portrait, which is quirky

The syntax highlighting is the killer feature for me. I spent literally one hour on the weekend on the phone in Nano debugging an unescaped double quote (as it turned out). In which case I need to request Javascript and QML highlighting...
