The multi-select feature is very useful.

One use case that would be useful to us is the ability to use multi-select to re-assign the puppet proxy to a group of hosts. Currently we have to script this via the API, or "manually" click each one and re-assign it.

The reason we do this is we have a couple of ways for hosts to be created (initial facts/report run, or via the API) and when we have to re-assign hosts to the "development" environment we want them to go to a different puppetmaster.
