Added persistent editor projects. Editing state is saved to <dataDir>/projects/<replay>.pbproj on Ctrl+S, from the menu, every 30 seconds, and when the editor closes; the replay file remains authoritative for the timeline duration.
Added replay of server custom blocks. Block types recorded in the StartGame packet are registered when the replay world loads and rendered with their recorded geometry and materials.
Added resolution of custom dimensions by their recorded name, so replays can reconstruct dimensions whose ids are not vanilla.
Added the recording game version to replay metadata. The replay browser refuses to open files recorded on a different Minecraft version and shows both versions.
Changed
Made keyboard input UI-exclusive while the editor is open unless the left mouse button is held over the game viewport. Escape no longer reaches the game; holding it for 0.8 s exits the editor and saves the project.
Kept the editor hidden until the replay world is joined and ready, so loading, resource-pack download, and sign-in screens are no longer covered.
Cut seek time roughly in half by draining chunk injection inline during catch-up and reusing already-applied snapshot columns.
Downgraded project save/load, keyframe capture, and custom block registration logs to debug.
Kept the configuration version, recording-file snapshot context version, and new project format version at 1; complete v0.2.1-mc26.20 archives remain compatible and require no conversion.
Documented that Vibrant Visuals is not supported yet; recording, replay, and export are only validated with the standard renderer.
Documented that 0.2.0 was skipped on the MC 26.20 line because video export stalled on that runtime, and that 0.2.1 is published for both runtimes.
Fixed
Fixed replays recorded by a newer build failing outright when a configuration packet had an unknown lifecycle; such packets are now skipped with a warning.
Fixed Ctrl shortcuts such as undo/redo never triggering because ImGui modifier state was not submitted.
Fixed the camera preview keeping a stale cached pose after a camera track was toggled.
Fixed timeline wheel-zoom anchoring to the wrong tick when the cursor was outside the canvas.
Fixed the property search box discarding typed text every frame.
Fixed a rewind keeping stale player-list skins instead of re-registering them.
