@gamey Of course I do know Waydroid and improvements to it would likely also be covered (if they're beneficial to any of the #Mobifree apps).
With the flatpak runtime I was rather hinting at something that is better integrated, i.e. by having Android apps turned into Flatpak apps, using Flatpak permissions and sandboxing and so on.
Anyway, I was obviously just dumping ideas to clarify that a lot of things can be funded.
