UI

Damix I'm sure they already are working on adding fluent design, after all we are only in the beginning of the Anaheim testing (just the start of development for MS Edge team as they started assuming it was in December, 2018 which has only made 5 months of development) at this stage. With time (and effort with feedback support) they will eventually add it, I would prefer however that Downloads has its seperate page as in my opinion I agree with how Chromium puts the Downloads in its own area so if I wanted to see my downloads I know where to go. For favourites and history, they should be integrated on the top bar as you said. Overall, Edge will eventually carry its old features over to the new but for now its pin pointing what's needed in this current stage.

Thanks for reading, peace :)
