Not auto-fixed in the per-pane PRs. The fragmentation spans the EQ pane's "Open settings.json" button (PR #53) and the Keyboard pane's inline Advanced (JSON) editor + its own "Open settings.json" button (PR #56). Consolidating to a single discoverable entry point is a cross-pane decision — e.g. keep the Keyboard → Advanced (JSON) inline editor as the canonical raw-file home and drop the standalone buttons elsewhere. Left as a maintainer decision so it can be done in one coherent change across both panes rather than split awkwardly across two PRs.
