Unclear on plan for the ui submodule

[flyaruu]

Hi,

I have some issues with the ui submodule:

1. The submodule seems to point to a ssh based checkout of the ui (which isn't public): here. I think that should be http based link, so we can all fetch se submodules
2. It looks like this repository was renamed, it points to cardamon-ui, which seems to redirect to cardamon-core-ui. I think those redirects don't last forever, but I'm not sure.
3. The cardamon-core-ui does contain the referenced commit, but the main branch is empty. Maybe merge something to main? Not it is a bit tricky to figure out how to iterate on that.
