Color in icons, will observe, have only seen in stablem.
FPS. I made an interesting observation, which has always been like this, I remember. I recorded it but can only upload in a couple of days. Happens in beta as well.
Edit a waypoint, then tap the circle/dot in order to choose a new position. The newly opened window is "nervous", like shaking or shivering, for maybe 1 or 2 pixels of distance. Vertically. Very subtle effect. If I then tap "from map center", the new map overlay window will be low fps.
But when I e. g. drag down the Android menu from the top, then put it back up, so Locus window re-appears in full glory, the shivering is gone. And then, the map window moves fluidly.

Edit.I checked the Favourits/App picker and I can definitely say, whenever the window is shaky, it scrolls badly. When it's stable, scrolling is smooth.
