To clarify, since this could be misleading: the UI extension is not a
Gtk UI extension, it can work with any toolkit or other form of UI,
including 'external' ones.

These can both be fixed without breaking backwards compatibility by
passing features to the UI.

I said the last time something came up with the UI init function that
things should just be passed as features instead of breaking the thing
every time we feel like adding a parameter for "convenience". That time
has certainly come now.

It should be completely port type agnostic, as it is now.
