When dealing with the Customize Node Details page and columns with multiple customized device pollers (see wonderful diagram below), there's no way to tell which poller item deals with which specific poller. I assume (hope?) that this is contained to the right of the entry; if not please include it and provide a horizontal scrollbar so we can see what we're working with. It adds a lot of time if one accidentally deletes the wrong item from a page and has to go back and re-add it.
