I made a screencast for my ideas about indetations, video here on a Chinese site:

And a demo which runs on Webkit browers (maybe there are small bugs).

Mainly about two ideas:
- If one line indents, the following lines indent too if neccessary.
- Guide line follows the caret.
Then we don’t need to select many lines one time to make indentations.
