In a new dev diary that went out yesterday, the team lays out a list of improvements for these systems. Dimensions will be getting a free-fly camera to allow for even more building precision, permissions options for visitors, ban lists, and -- prepare for this to blow your mind -- a bigger +1 button.
As for minions, players will have even more options in how they deploy these hard-working followers. The team is adding minion stamina potions, the ability to shuffle adventures, and the option to link to minions in the chat window.
