@paul_irish A simple, but handy feature idea for @ChromeDevTools : Emulate a functionnal mobile keyboard when you focus a field (text/passw/number/email/date/...), so you can understand -when coding a PWA- the implication of having half of the screen used by a mobile keyboard.
Good idea, I've heard this one a couple times. In Device Mode I thought it was possible to block out a portion of the screen. It doesn't show a keyboard, but it blocks out the space that the keyboard would take. Maybe I'm mistaken...
