Thanks to @elasticthreads I’ve just found out that Quicksilver b57 is available. The popular app launcher has finally gone out of the alpha and seems like it re-emerged with a group of open source developers. I’m gonna look into this.
I’m testing this new beta right now and it feels faster than ever. QS has indexed my Mac in less than 1 minute and overall the app is so very stable.
Anyway, here’s the official discussion. You can download the latest build here.
