The GNOME application launcher lacks flexibility and usability. For example, if the name of the command or application to be executed is composed as chromium-browser, you need to type chromium-bro to make it autocomplete, so I have decided to replace it with Synapse: a semantic launcher.
Synapse is an excellent alternative to the GNOME app launcher since its search algorithm is much more exact and efficient.
