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.
Con Extensions store is confusing, lots of redundant extensions.
There are dozens of extensions, which is good, but as an average user it is hard to find what you are looking for. It is unclear to me how updating plugins work.
Con Needs more posibilities for extensions
Currently, extensions can run only when you type their alias and <space>. There is no way to see results from multiple extensions at once. The output is also limited just to rows.
Con Does not easily fit into a customized desktop without full GTK3 CSD support
