Tooltip not showing on file:// protocol on Mac OS X

Option to open as a new window

One suggestion: Would be nice if we had an option to see the actual size of the site, discounting the nav bar of the browser.

Resizes to the wrong dimension

Does not work with zoom.

Presets don't stick between El Capitan & Sierra on the same monitor

Feature Request: Tooltip positioning options

doesn't work for chrome Version 54.0.2840.87 m (64-bit)

Doesn't work in version 54.0.2840.71

feature request: add the ability only change the width of the window/viewport, and maybe also the option for only change the height. thanks for the good work so far on the resizer.
