Aloha A while ago Aleix created an appstreamrunner allowing you to find applications (from appstream data) via krunner and install them (by invoking whatever software center is associated with appstream URIs).
There was some consensus that it would be nice to have but we never reached a decision where to put it. I am proposing that we include appstreamrunner in plasma-workspace and enable it by default. It only depends on appstream and can use any old appstream-enabled software center (discover, gnome-software, what have you) and it makes sense in pretty much every form factor scenario (e.g. if mobile launcher has a search it can equally display apps for installation if no installed software matches the query). I've been using it since the very first day and simply love it! Software at once's fingertips, what more can anyone ask for. HS
