Yeah that's certainly a valid point. I've tried to account for this on smaller viewports by having min width for the board set to like 400px I believe.

I guess setting a minimum column width could be useful, on the other hand you kinda don't want people to have loads of columns because you want to keep the amount of things you're working on to a minimum right?

I'd be interested to see what people think is the best approach to this.

Thanks again for the feedback, it's much appreciated.
