Our default iconset called Pocillo uses Moka Icons for all applications.
This has had a substantial update to catch up with GNOME 3.32/3.34 and what we know of 3.36 GNOME application icon name changes.
So look out for this and let us know of any applications that had moka based icons in 19.10 but no longer have moka icons in 20.04.
As an aside - we are looking for anyone who is interested in continuing development of moka icons
- the upstream maintainer hasnt really done any substantial work on the icon them for a few years now.
