Player - Arrow keys seek by 5s, Shift for a 30s jump on long recordings, J/L for +-30s, Space toggles playback, and up/down adjust volume. Dragging a scrubber across a multi-hour replay is unusable — one pixel is tens of seconds — so keys are the practical way to move around a long recording. - The shortcuts ignore key events from inputs, so typing a chapter time in the replay editor no longer scrubs the video. - Add a playback speed selector. It is a replay tool: speeding a live stream up would only push it further ahead of the encoder's buffer. Replay editor - Stop playback restarting on every edit. The player's source effect depended on the `lines` and `qualities` arrays, and callers such as the replay editor pass fresh literals on every render, so adding a chapter or typing a title was treated as a source change and reloaded the stream from the beginning. The effect now depends on the resolved source URL instead of the arrays it came from. Measured: adding three chapters leaves the media requests unchanged and the playhead advancing. Settings persistence - Settings edited in the UI were applied to the in-memory settings object and never written down, so the brand, transcode ladder and load-balancing strategy silently reverted to the config.py defaults on every restart. They are now saved to backend/settings.json (atomic temp-file replace) and re-applied at startup, with only known keys accepted so a hand-edited file cannot inject arbitrary attributes.
