In FM16 Layout Animation was introduced which is a fantastic feature providing a richer experience to users both on Desktop and on iOS. The layout animation brings FileMaker & FMGo closer to being on par with native applications.
Although this feature has literally changed the way systems are designed I think the experience could be further enriched by combining both layout animation and card windows.
There is one native function that is still hard to replicate in FMGo which would really transform the users experience. The sliding left vertical menu.
I believe by combining layout animation on iOS and card windows would finally allow users to experience this now very normal feature in FMGo applications.
