Adding a server no longer opens with a tick list: a fresh node keeps every album its key can see — the empty album list the backend stores for "all of them" — and narrowing is a change made on the node that is already there. The album-ID field carries the warnings that were silent before it: a line with no id in it, and an id this key never named, both said where they are typed. A node's key can now be replaced in the dialog that narrows its albums; the backend probes it first, so a key that does not answer leaves the node and the dialog as they were.
