Cons
Con Synapse is an abandoned project
The latest release was 7 years ago and the Launchpad page is a ghost town
Con Unable to search whole system
Due to Zeitgeist being used the search is not as robust as if it were using Tracker. Of course using Tracker has its own downside like battery drain, so currently there is no "best" solution.
Con Bound to control+space
Due to this it interferes with common IDE layouts for recommendations. Modifying hotkeys file doesn't adjust this.
