For example, I am rolling my own window manager (that needs some much needed TLC). I ditched Alfred for Spotlight. Though Alfred is better, I will survive just fine. And the list goes on.
I am not trying to take a dig at the OP. I am sure he or she put effort into this application. But I am genuinely curious -- does anybody actually need this software? Cmd+Tab, a decent window manager, and Spotlight would solve the same problems for free.
