IzzyOnDroid is a repo compatible with F-Droid that has a huge amount of apps.
There are very interesting apps, such as Osm Go! that are not installable if the repo is not added to the client.
Even more, sharing an app link from that repo gives error to other users that do not have the repo added.
So the question/petition is: if there are already external repos such as Guardian Project, why not add also IzzyOnDroid by default, considering that it has many-many interesting apps?
