I would like the ability to be able to set NCrunch to only build my solution and run my tests after a new line of code is entered or an existing line of code has been edited.
I find the feedback I get from VS more than enough while writing my line of code and would much rather have NCrunch working on giving me feedback on my solution up to the point where I added/edited the last complete line of code while typing the next.
This would allow me to run many more test (as NCrunch has the time between typing each line instead of typing each character) and it wouldn't use up resources trying to build a project that isn't buildable.
