I was using Gnome on PureOS for a month or so, but now I'm back on Ubuntu 18.04. The thing I loved in PureOS is that I could do calculations in the Gnome search bar. But when I type any calculations (
1+2) in the gnome search bar I see no results (it says "No results" in Dutch):
I tried this gnome extension and it's enabled in Gnome tweak tool as you can see below, but I see no results (I rebooted to be sure).
Does anybody know how I can activate calculations in the Gnome search bar?
