Twitch Portrait Mode — Vertical layout + wheel volume

What it does

Shows Twitch in a tall (portrait) layout when the window is narrow.
Chat becomes a full-width strip below the player.
Drag the handle at the bottom of the player to change player height.
Scroll over the video to change volume (configurable step). Middle-click toggles mute.

Menu

Enable Portrait Mode
Set Threshold (width/height ratio)
Set Volume Step (enter decimal like 0.05 or percent like 5)
Reset Player Size

⚠️ Important — Portrait mode requirements
Portrait layout only activates when the browser window is narrow (width/height ratio below the threshold) and you are in Theatre Mode on Twitch. Make sure to enter Theatre Mode (theatre) and resize your window so it's tall/narrow for the portrait layout to appear.
