This actually is my experience with the v3.0 Devices tab. I just compared it to the v2.5x Home tab on a phone that I haven’t yet updated, and the only significant difference is that after displaying the order I’d already set in v2.5x (where many things were in groups, even if the “group” was only a single device), the v3.0 list went on to list the remaining group items broken out as individual items. I actually like the way this was handled automatically and think it’s really smartly done, especially in anticipation of the time when Wyze rolls out the ability to put a single device into multiple groups.
The main addition I’d have from my own observation is improving and increasing the use of contrasting color cues:
I mentioned other things in that post and elsewhere that echo some things on your list, like allowing users the option of cached thumbnail images for cameras on the Favorites tab (instead of the automatic live stream attempts) and allowing users to choose the Devices tab as the default Home screen. I’d also add the ever-present requests for full landscape mode and full dark mode, but I imagine those are probably still (already) works in progress.
