I have a small suggestion concerning the default code for the macros.
It should have 4 spaces for the indention, as per PEP8. I realize it's
merely a matter of preference, but probably best to present Python
code in a standardized manner.


I really like the QgsMessageBar class. Definite improvement to the
GUI. It will be very useful and unobtrusive, compared to dialogs
popping up all the time. Nice work making it non-blocking and so the
canvas doesn't have to re-draw.

I can see several changes to the message bar that might help, for more
general app use:

- Simple means to 'scroll' (maybe just one way) through multi-line
messages, with close button only for total close of message(s).
- Easy means of passing QAction(s) to one or two buttons (like your
Enable button).
- Customize icon, background color, height, etc. via calls.
