I think there needs to be a quick disable option to turn off Start8 if needed....example; when trouble shooting for issues of the OS that require 3rd party apps to be turned off to check the multi-window snap feature. Where you can run more than one metro app on a single screen.

I did find the start8tweak.exe application....it's a bit hard to find and cumbersome to use but it works. I still would prefer a one click disable solution. I sure hope that the developers are looking into this option.
