Neutralise upstream commentary, and make screenshots readable Describe upstream PR states as facts (open, merged, closed without merging) and drop the asides about how proposals have been received. Split the three-across BPM detect screenshot into three cropped images, one per step, and stack the box selection screenshots vertically, so the UI text is legible at wiki page width.
Document the fork's features and fixes Adds a page per area (3D View, Show Manager, Show Tempo Sections, Function Manager, UI Settings, Fixture Library, Engine and Playback Fixes), a sidebar for navigation, and screenshots. Each page separates what is already merged upstream from what is only on the fork, and notes the upstream PR and its state per entry. Fills in the existing Home page's feature and fix sections.
