Support for flip phone cover screen usage

Use case or problem

obsidian not marked as applicable for cover screen (the back side mini screen next to the camera lens on flip screen android phone, also known as FlexWindow for Samsung phone or outer screen for motorola phone)

Proposed solution

just mark it as usuable for cover screen if it is simple as turning on a flag or implement the callback api etc. Should be pretty simple bc just need to render app in smaller size which fits the cover screen size
