eloimovo/better-dsh-codex-effort-slider

Takes over the model button in the DSH composer and opens its own two-level panel (provider list, then model list with search) built around a continuous draggable reasoning-effort slider: the fill runs blue to violet, higher levels add nebula and dust particles, and every level has its own color. Drag moves one level at a time, and picking a model keeps the panel open and repositions the slider to that model's middle level.
