Let's discard the adapter/shim (main goal is to reduce the dependency).

Isn't there anything that we can do to reduce the dependency. Especially
with Gtk.

Why aren't CollabWrapper and SugarGame very common between activities?
Especially CollabWrapper.

If CollabWrapper is simple, why not expanding it?
