I’ll be honest, it took me awhile, and I still have and use Alfred. The problem was that they just behave differently. I was trying to use Launchbar with an Alfred mindset, and they are just different. What made the difference was 1) Setting shortcuts manually, this was huge for consistent behavior and 2) Tweaking the Index. Much of my problems came from searching for things I not yet indexed.
As a longtime LB user, I’m interested in trying Alfred. With LB, it feels like what I want to access is rarely the first, second or third option. I know I can set abbreviations, but that is laborious. I’m intrigued to hear if your experience is different.
