Hi, I have used alfred 3 without powerbacks for a while now and I am thinking about upgrading to powerpack but I do have two questions. First question: About the mega supporter lifetime upgrades license. If I buy that one does it mean I get free upgrades to for example alfred 4, whenever and if that releases? Or is it only larger upgrades within alfred 3? Second question: Since the mega supporter lifetime license is a single user license, does this mean that I can only choose one unit or can I switch units as long as it is only 1 unit active at a time. So lets say I use it on my macbook pro and then later i get an Imac and I want to use alfred 3 for that, will I be able to change which unit that is active? Thanks in advance!
