VisioNext — adaptive Visio layout louije מאת

On Visio (La Suite numérique, built on LiveKit), when someone shares their screen everyone else is squeezed into a single scrolling column. This extension reads the shared content's real aspect ratio and lays the participants out intelligently: beside the screen or below it — wherever the grey letterbox bars leave room — in one or two lines, so you can see more faces at once. Toggle it on or off from the toolbar.
With the companion VisioNext macOS app, its global shortcut also mutes your microphone in every open call at once: Visio always, and Google Meet or Teams if you allow them in the extension's settings (each site asks for access once).
