Many of us are waiting to upgrade our OS to Big Sur because we rely heavily on Mailhub. Others have already done so mistakenly and are frustrated. This is an opportunity for you to bring up a new version that I am sure your faithful followers and users would be happy to pony up some dollars for. Can you, at the least, do us the honor of informing us if you intend to continue developing this glorious product and, if so, when you might anticipate a beta or even an alpha version? We appreciate you!
