Any curious #Android users around? I just pushed the first early-bird code of my little sync tool to

codeberg.org/izzy/adbsync

Can be used to sync some data (documents & co, not intended for system stuff) without needing any app on-device. Uses rsync & adbfs (some details in the readme). You define per-directory whether it shall sync from or to the device. Supports bidirectional as well, but use that with care as it's rather hacky-wacky.
