In article 20180726083240.Horde.yz7MtOof32nSSRySE90tb_S@andreasschulze.de you write:
Another is to provide different views of what lists exist depending on what IP address you're connecting from, so internal lists are only visible on the internal network.
you could let the webserver control the access to specific URL but that may be painful if you have many lists.
I think it needs more than that. There's a page that lists all of the lists which needs to show different results for internal vs. external.
Does anyone else think that views would be generally useful? If I do this I can probably contribute the patches back.
