@trezzer I really wish Apple would give 3rd party keyboards more/better access to things because they all suck. The typing experience could be so much better.
I too am wishing for the same thing you are. iOS (for the apps and ecosystem) + Niagara Launcher + Android keyboard. That would be my perfect device.
That and the action button to be moved bellow the volume buttons (don't move the volume buttons up, just move the action button to bellow them instead of above them for better reachability). I have my action button tied to a shortcut that detects what app I am using and does all kinds of crazy things for various workflows. It is SUPER powerful once you take the time to set it up.
