It feels strange to see features in Windows 10 mobile removed, maybe I'm wrong but I think that upgrading should add new features along keeping the existent ones. There are nice new features present in mobile redstone builds, but I still find stuff removed really bad decision. I miss the most FM radio, which was great and have never encountered any bug with that app. People integration for apps like Twitter I also miss to much. There are lots of other stuff that got removed without any clear explanations, yes there are workarounds like using Tunein in case of FM radio, etc. Features like swipe left/right in browser got added just recently while not being present from the start. So what's your opinion of that? Does the introduction of new/old feature really improve the OS while removing old features? What do you miss the most?
