Measurement ideas
Track completion rate from URL paste to successful download (or honest failure). Segment by device class to see whether performance tuning tips changes outcomes on phones vs desktops.
If you publish changelogs, reference guide #220 when you ship related fixes so internal search stays coherent.
Explaining stereo vs mono audio exports
Lecture recordings may be mono voice tracks. Downmixing stereo music to mono incorrectly can phase-cancel; expose a mono-friendly preset when you detect speech-heavy content.
Label channels clearly in advanced export dialogs.
Explaining loudness normalization for audio
YouTube applies loudness targets; ripping raw streams may sound quieter in a local player. Optional loudness normalization should be opt-in to avoid clipping.
