Libcamera development is probably the most exciting thing for me. Phosh is pretty usable as is now and web browsers work fine on Linux mobile, but camera support is a giant mess with v4l2 and having to manually wire up the camera pipelines in a device-specific way. Offloading said mess to a library and having a standard API for applications to use for camera access should allow for easier integration of mobile cameras into apps that already support USB cameras (uvcvideo). I know the PinePhone has partial libcamera integration already (qcam works but not well) and the PinePhone Pro also has partial support as it shows cameras as available but have not been able to get a picture yet.
