I was sad to discover today that the HUD is back to what it was. I really enjoyed the new design, as the old one is much more cubic and everything is so big. Reading the comments I understand why Inno reversed the update, that's why I would like to leave a comment myself, to give a positive opinion.
I play on Samsung Galaxy s20+, and I like that the icons were smaller, because I was able to see much more. Only 2 problems I had were:
1) that chat icon often got in the way because of the awkward position on the right side of the screen,
2) and when clicking on the arrow in the bottom right corner to unfold the options, like Great Buildings, the arrow sometimes changed its position 180* and wasn't working until I revisited the world.
Anyway, thank you Inno for a great design, and even though the announcement says that you don't have plans to go back to it, I hope that maybe in the future it will be available again. Maybe in 2 or 3 size options, for people with smaller screens/bigger fingers? The old design is also fine (but worse than the new one, in my opinion). I started playing on mobile last year, and after that, tried FoE on the computer and was very confused at first. Now I play in the browser more often, but I still find the HUD a bit unclear. Would be good to find some changes in the design there, too. Especially icons, which are really mysterious for me. I get use to it of course.. but, you know.
Great work with the new design on mobile and I always welcome new changes in the future. Cheers!
