This is very annoying. There is no option (in the iOS app) to sort favorite keys and they also do not keep the order of when adding them. Even worse, the favorite keys are randomly mixed and also the macro keys are sorted in at an arbitrary place. For example, I added the num keys as favorites for my X1, and they now show in the following order: 1-2-Macrokey-3-4-0-5-6-8-7-9. This is usability at its worst! And I first added the macro, then 0, then 1-2-3, then the rest. The order is broken whatever I'm trying to do!
