I'm eager to use the mirror card function in my paid account, but we have numerous projects and numerous people working on each project. I will quickly create a lot of mirrors - this was one of the reasons I didn't buy the power-ups (they became too expensive, or didn't offer enough mirroring instances). So, is there a limit to the number of mirrored cards I can have in a workspace? Is there a limit to how many times I can mirror the same card?
