I just remembered, that my biggest suprise when switching to sfos was, that I couldnt always see the current time on the screen.
Right now I was browsing the web, and just slided from the right edge to see the time half transparent. this behavior is now perfectly fine for me, once i got used to it. I got to like the additional screenspace (although notifications are an issue sometimes) and checking the time is perfectly easy.
I dont know if the tutorial to sfos got improved already, but I would guess, that this is a thing where many people stumble. So either I was just missing out on that part, or it might be a thing that could be mentioned more specifically in the tutorial as it is a common thing.
