As the most loyal to the blog you will know I am an unconditional fan of QuickSilver although its development is in limbo and there is no news, but there are always alternatives that can be taken into account.
Berokyo presents us with a different concept, since it is a desktop organizer and an application launcher that allows us to adopt a new way of working with our computer, since until now it is difficult for you to have adopted their methodology.
It is very customizable, it has incremental search, drag & drop support and the organization can be fantastic… but I stay better as I am and with $ 18.95 more than if I had bought it.
