I've read about this in the community, but I need to ask again: Are there any low-cost solutions for syncing cards between boards? Unito isn't an option.
However, I'd like to hear from Atlassian why they haven't included such a basic feature in their product. It doesn't make sense to pay more for a third-party power-up than for the enterprise subscription. Without it, Trello is just a simple task app.
