I installed this app last night and it seemed to run fine, although i'm not sure what the real benefit is over spotlight. I decided to keep it anyway as I quite like the application launcher side of things.
Turned of mac before bed last night and went to boot up this evening after work and mac kept on kernal panicking. Tried to resolve but could not and now i'm faced with reinstalling everything all over again after a clean OSX install. Lucky for me it's the Easter weekend and I a) have the time and b) have pretty much everything I need backed up.
I can't say for sure that this app caused my problems but I now for sure everything was fine beforehand and this was the only installation carried out yesterday.
Therefore, tread with caution.
