Automatic gold key rollover
I hate interrupting my treadmill workouts and walks to keep checking my phone to see if a portmanteau has finished and then starting another and then watching that it’s actually registering my activity . I would love the possibility of designating a string of 1km portmanteau to open one after another with the gold key automatically. I save silvers for the bigger ones but often have all slots full of 1km ones. Being able to set the gold key to always open the next available 1km by default would be even better, but being able to choose the next 5 in advance would suffice. Hope the designers will consider that.
