Impressive work, thanks a lot!

I do not have much to say, it looks like you spend quite a lot of time testing this and it is working very well.

My only concern is about the two tabs we have on the main page. I'm not sure they are really useful anymore. But I will open a dedicated issue on that, since this needs to be answered by more people than the two of us, and having ZIMs to showcase the situation is probably going to help.

I will rebase and merge right away.
