@mathuo - I forked and pulled these changes and resolved the conflicts against master and this appears to help address some of the needs we have, is this something I could help push forward?

@david-tsai-skydio for sure, if you have a branch feel free to raise a PR and I'll make some effort to get it merged. Doesn't have to be perfect, happy to clean parts up
