I like the idea of using Thought types much more actively - to indicate the status my thought (I like that the icon changing visually to) - but that means changing them a lot all the time (like tags - but tags do not effect though icons) - That would mean only 1 mouse click instead of 3mouse clicks everytime I would change though type.
(66% less clicking)

I got the idea your webinar: From Thought to Insight - Mastering Your Tasks and To Dos with TheBrain - This recording features Seeds of Knowledge Winner Omer Aziz, Manager, Nortel Networks & GTD Enthusiast.
