External tool rows are not part of Akron's base overlay tabs. They appear only when the relevant mod is loaded, and they are documented separately so the main feature pages stay focused on Akron's own options. Motion Smoothing adds FPS and TPS bypass rows to the Global tab. Its higher-FPS path keeps Celeste physics at 60 FPS while drawing extra frames, so Akron marks FPS Bypass and the physics-neutral smoothing options as **Regular clean**. Object interpolation is stricter because Motion Smoothing documents that it can add 1-2 frames of input delay. Extended Variant Mode can also expose variant-specific rows at runtime; those dynamic rows depend on the installed Extended Variant Mode option list. Extended Camera Dynamics adds camera status and ECD-backed zoom-out support for Akron Cursor Zoom when its own camera hooks are active. Akron still uses its native Cursor Zoom path for zoom-in and neutral zoom. When Speedrun Tool is loaded, Akron also exposes **Ignore SRT** inside the Lag Pauser option menu on the Level tab. That setting is documented with Lag Pauser because it changes Akron's lag-spike filtering rather than adding a standalone Speedrun Tool row. | Tool | Option | Control | What it does | Attempt status | | ------------------------ | ---------------------------- | -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------ | | Motion Smoothing | FPS Bypass | Numeric toggle | Raise the draw cadence or enable Motion Smoothing's smoothing pipeline while keeping physics at 60 FPS when TPS Bypass is off. | Regular clean | | Motion Smoothing | TPS Bypass | Numeric toggle | Change the simulation tick cadence. | Cheat | | Speedrun Tool | SRT Status | Action | Show whether Akron can read Speedrun Tool status, slot state, and room time right now. | Regular clean | | Speedrun Tool | SRT Slot | Action | Show the active Akron slot used for Speedrun Tool state capture and restore actions. | Regular clean | | Speedrun Tool | SRT Capture State | Action | Capture the active Speedrun Tool state slot. | Cheat | | Speedrun Tool | SRT Restore State | Action | Restore the active Speedrun Tool state slot. | Cheat | | Speedrun Tool | SRT Clear State | Action | Clear the active Speedrun Tool state slot. | Cheat | | Speedrun Tool | SRT Room Time | Action | Show Speedrun Tool's current room timer value when its room-timer export is available. | Regular clean | | Speedrun Tool | Export Room Times | Action | Export room-time data when the optional room timer source is available. | Regular clean | | CelesteTAS | TAS Status | Action | Show whether CelesteTAS reports an active or currently running TAS. | Regular clean | | CelesteTAS | Configured TAS File | Action | Show the configured TAS file basename used by Akron's CelesteTAS handoff. | Regular clean | | CelesteTAS | Play Configured TAS | Action | Start CelesteTAS playback for Akron's configured TAS file path. | Cheat | | Extended Variant Mode | Reset Extended | Action | Reset all non-vanilla external variant settings to their defaults. | Regular clean | | Extended Variant Mode | Reset Vanilla | Action | Reset external vanilla variant wrappers to their defaults. | Regular clean | | Extended Variant Mode | Extended Variants Master | Toggle | Toggle Extended Variant Mode's master switch when the mod is loaded. | Goldberry/Hardlist clean | | Extended Variant Mode | Extended Variants Randomizer | Toggle | Open Extended Variant Mode randomizer controls when the mod is loaded. | Cheat | | Extended Camera Dynamics | ECD Status | Action | Show whether Extended Camera Dynamics is loaded and whether its camera hooks are active. | Regular clean | | Extended Camera Dynamics | ECD Zoom Out | Toggle | Allow Akron Cursor Zoom to zoom below 100% through Extended Camera Dynamics when its hooks are active. ECD zoom-out stays centered on the player; native zoom-in still uses Akron's cursor-focused zoom path. | Cheat | | Extended Camera Dynamics | ECD Restore Zooming | Action | Return Extended Camera Dynamics to automatic zooming after a forced camera focus. | Regular clean | ## Option menus Rows with a triangle expose the controls listed below. | Option | Menu control | What it changes | Attempt status | | ---------------------------- | ------------------------ | --------------------------------------------------------------------------------------------------- | ---------------------------------------------------- | | FPS Bypass | Target FPS | Set the draw target while FPS Bypass is enabled. | Regular clean | | FPS Bypass | Method | Choose interval or dynamic render cadence behavior. | Regular clean | | FPS Bypass | Smooth camera | Choose Fancy, Fast, or Off camera smoothing. | Regular clean | | FPS Bypass | Objects | Choose extrapolate or interpolate object smoothing. | Regular clean for Extrapolate; Cheat for Interpolate | | FPS Bypass | TAS mode | Keep overworld updates locked for TAS compatibility. | Cheat | | FPS Bypass | Subpixel Madeline | Draw Madeline and held items at subpixel render positions. | Regular clean | | FPS Bypass | Smooth background | Use high-resolution background compositing in Fancy camera smoothing. | Regular clean | | FPS Bypass | Smooth foreground | Use high-resolution foreground compositing in Fancy camera smoothing. | Regular clean | | FPS Bypass | Hide edge gaps | Slightly zoom the level to hide gaps introduced by fractional camera offsets. | Regular clean | | FPS Bypass | Nasty mode | Apply the experimental smoothing preset that Motion Smoothing recommends avoiding in real gameplay. | Cheat | | TPS Bypass | Target TPS | Set the simulation update target while TPS Bypass is enabled. | Cheat | | Extended Variants Randomizer | Change variants randomly | Enable the external variant randomizer loop. | Cheat | | Extended Variants Randomizer | Reroll mode | Replace the randomized variant set instead of changing one option at a time. | Cheat | | Extended Variants Randomizer | Display enabled variants | Show the active variant list on-screen. | Regular clean | | Extended Variants Randomizer | Interval | Set seconds between randomizer changes; zero uses screen-change behavior. | Cheat | | Extended Variants Randomizer | Max | Set the maximum number of simultaneously randomized variants. | Cheat |
