I work for both desktop and mobile screens and I would like to save custom frame sizes and have them under a custom category. basic desktop sizes like 1366x768 is not available in the presets and the desktop category only has Mac screen devices as options.
Agreed! Having only Mac screen sizes is an incredibly privileged and myopic view of technology. Either add more sizes (like a Chromebook 1366x768) or allow us to save our own presets.
