Eric, could you please take a look?

There is now a CL in review to make orientation preserved across switching devices!  https://codereview.chromium.org/2431823002/

For zoom preservation, I think this is less clear to me.  The current fit-to-window logic supports devs who want to see the entire device.  This makes it easy to quickly see how a site looks overall, especially when switching between phone/tablets.

Please help us understand if there's a strong use case to make zoom preserved as well.  We can also see if there are more stars / opinions for turning off auto-fit-to-window.

My original tweet was only about zoom, not about the device orientation. When I'm trying to check that the elements are right, for me it's much better a 100% view instead of a zoomed blurry view where I can't check things correctly.

I doubt that this issue would get many starts because I don't think that the most of the developers will even find it to step up and agree or disagree with it.

The best solution would be something "intelligent", like remember the last option that the user has selected in the zoom combo instead of resetting it (ie: don't reset to neither 100% or autozoom), or even remember the zoom factor of each device.

Surely there are correct use cases for both autozoom and 100% zoom, so any solution that forces one of them will cause pain for the developers that want the other situation.

At the moment I think that remembering zoom  and rotation of each device might be the best solution.

Sounds good to me.  I'll update the CL with last-zoom-for-device, where each device remembers the last zoom it used.

DevTools: device mode devices remember last used zoom

Before, switching devices in Device Mode would set the zoom scale to fit the
window. Now, devices will remember their last used mode.
