When I'm processing a lot of notes I'd like to more easily navigate between notebooks, notes and tags. Nixnote could be set up in much the same way as Gmail. It would require that by pressing the ESC key, the focus was removed from all fields. That way a lot more flexibility and ease will be available when pushing shortcuts.
Here's a quick example
#. Key(s) Pressed | Description
1. ESC | remove focus from the current field
2. g | signify that you want to "go to"
3. n | specifiy that you want to go to a notebook
4. Inbox | inally some auto-complete text field would pop up that's populated from the current set of notebooks and I could start typing the notebook I want to go into by typing for example "Inbox".
