As BANanoDesignElement was only released two weeks ago, my suggestion is to do whatever is better in the long term. BANano is new enough to be considered in "beta state" and not suffer from the burden of infinite backward compatibility.
mmm, maybe I better hadn't started the poll and just used common sense as it is indeed considered in "beta state". The new system will be so much better. Can't really close it so I just set it to 1 hour.
