Pressing Add button doesn't immidatly add the page

[jsparber]

I tried to add https://listen.tidal.com adding the page by pressing the Add button didn't do anything visible but after pressing it several times multiple pages for Tidal were created. I guess it was just slow at creating the page for some reason. I think it would be great to add immediate feedback e.g. with a spinner (in Fractal, we replace the button label with a spinner and make the button in sensitive).
