+- **feat: Steamify app (v2 UI)**
+  - A graphical app for controller, keyboard and TV remote, driving the same
+    components through `steamify.sh --backend`; the BIOS update with both
+    warnings; built by GitHub and run with curl.
+- **feat(ui): HDMI refresh boost in the app, off only**
+  - Each step needs someone at the keyboard, so it's turned on from the
+    menu in Konsole; the app can only turn it off. Unticking Steam Machine
+    support or the kernel pin unticks it, as in the menu.
