To run simulations on individual devices rather than globally, open the device menu by clicking the 3-dots icon on the top-right of the device, and click on Simulations.
Just like in global simulations, you can now mix and match the simulations that you want to run on individual devices.
To help you identify which devices are currently running simulations, Sizzy shows a 🧪 Test tube icon above each device.
To modify the active per-device simulations, click the same 🧪 Test tube icon above the device, and toggle the ones you want.
