Device emulation on dev panel?
This feature is a must that I still miss from Chrome and I wonder if you can enable it. I'm sure I am not the only one that uses it and misses it.
Keep up the great work!
⋮ menu (Customize) in Devtools
Dock to window
The you can open the emulation.
If you're having trouble finding it, it's not listed as "Emulation", but you may enable it by clicking the 2nd item on the left of the top bar when docked. It looks like 2 rectangles next to each other, and the tooltip is called "toggle device toolbar".
If that still doesnt work, press Ctrl+shift+M when the dev tools is docked to the page.
