FluentBoards looks great. Feels very familiar. We are big users of Trello currently. For better or worse this is going to compared to Trello as the metric.

One of the first things I noticed is that there is no way to duplicate a board. Currently in Trello we have a workspace full of template boards that we duplicate for a variety of use cases.

For my company and our clients, we would probably have limited uses for this until it has a system for automation.
