Weather on the clock
Clicking on the clock reveals various things like calendar (The current date is shown on the clock), Do Not Disturb button (Showing an icon letting you know it is active on the clock) and also notifications (showing an indicator that there are new notifications on the clock). Something quite interesting is when having GNOME Weather app installed, the current temperature is shown on the clock.
I was doing an extension for this, it was at an early stage and I gave up on doing it as it would honestly be so much nicer to have it upstream.
