This is truely awesome! The whole "no gear, no crew, no subscriptions" thing is kinda genius imo. Solo lens calibration sounds like a lifesaver for indie projects like mine – no more begging friends for help! So, how's the Python script integration? Is it easy to pick up even for someone who's not a Python whiz?
