Enable to choose between thought search and full brain search
One thing always bothered me on the PersonalBrain and still on TheBrain 7, is the search feature. I find it very annoying that it is a combined feature. I think many Brain users like me more often use the search for thought feature within that entry field rather than the search for content. Both very useful features, however I don't think it is very good practice to combine these two features in one entry field. Especially when having larger brains, that leads actually to unwanted waiting time as there is also no way to interrupt the search.
So requirement 1 would be to have the ability to choose which kind of search I want and second requirement to be able to cancel the full brain search.
