Testing on foldables is always like "how the hell did this got there?"... "oh.. yeah, It makes sense".

I love my Pixel Fold
Send me good app designs that you are using on the big screen. Right now Amethyst on Fold is just a scaled up version of the app. We can do better, but I don't know what's good in that form factor.
I was thinking about this some hours ago. It will really be useful.
I have an old Surface Duo phone from Microsoft that probably doesn't have any battery life left, but if it would be helpful I could boot it back up and test things. Though knowing Microsoft, the tech they used for two screens is completely different from modern foldables.
