You mean that you have two hops and the first one requires key and the
second password authentication? I am not sure about your setup. But
basically at the moment it is possible to use more hops only if there is
the same key on every hop, or keys without passkeys.

Didn't think about that. :) Now it shows on which hosts it runs. I can add
a number next to the hosts, how many times it runs on the host.

The "Show log" works only for default log locations, obviously this will
be fixed at some point.

You mean something like crm configure erase? This will be added soon.

It would be possible, but somehow it doesn't strike me as something that
is done very often. For what would you need that?
