I'd love to hear from somebody who knows better, but my understanding is that the legal aspects of look-and-feel ripoffs have never been settled in court.

In one sense, that doesn't matter. Trello has way more time and money, so I'm sure they can sue the LibreBoard people with enough vigor that the LibreBoard folks will decide it's much easier to come up with their own look. Whether or not LibreBoard could eventually win the suit is irrelevant if they can't afford to go the distance in court.

Of course, it probably doesn't look great for Trello to sue a couple of random dudes, so I could see them letting it go. Or perhaps just calling them up and talking developer-to-developer about how this makes them feel as creators and asking LibreBoard to do their own work.

Actually they were litigated as part of the Lotus v. Borland suit which a distant cousin of mine (same name, common ancestor is like 4 generations back) was involved in, I sometimes get inquiries)
