I just found out about SilverBullet and it looks promising, but I'm also worried about the lack of a dedicated app for the same reason as you. The developer mentions installing it as a WPA in the demo video, have you tried that? Seems like it could solve the shortcut problem.

Are you somehow able to lower refresh rate below 60Hz on phones? Would love to do this if possible (have an Android)

e: There's adb command to change the refresh rate: `adb shell settings put system min_refresh_rate 10.0`. Unfortunately my phone seems to have locked possible refresh rates to 60/90/120, any other values don't do anything. If someone wants to try this, there should be "Show refresh rate" setting under developer options which helps to detect if the adb command was successful or not.
