Absolute must have !

If there is one application that makes a difference for everybody and improves things for everyone, it is Alfred.
No matter what software one is using for productivity or daily simple tasks, there is either Alfred or an Alfred extension for it.
Everything becomes simpler and faster and by that I mean really EVERYTHING.
One becomes rather lazy, which is probably the only (but by no means negative) side effect of using it.
The best thing, which matters most to me, is that it is rock solid and simple. The ergonomics of an application are often shamelessly overlooked.
