To clarify, what you mean is to do a search and have the results add to the current result list instead of replacing it? Or you could mark individual stations on a result list as pinned and they would remain regardless of what searches were performed? That does sound useful. Thanks.
Yea, the second way you described it. I mark a station and it stays in the list when I do another search. I actually expected this when I "collapsed" my first search result.
