I don't think mini have bed adjuster on it, but add one with heated bed is not difficult.
My feeling is miniMaker automatically bed leveling works better than Jr.. But I still prefer manual bed leveling.
Some reported miniMaker don't recognize paper tag after firmware upgrade, but the cause is not confirmed. If you don't want to learn how to downgrade firmware, you should wait for more information. If you accidentally upgrade the firmware or xyzware upgrade it for you without your permission, here is the guide how to downgrade to 1.2.3

if you don't want to risk get upgraded by accident, try David's miniMover, it is free, fast, easy to use, so much better than xyzware. And it will not make your miniMaker auto-upgrade.
