Does work except after closing the browser it doesn't save it to stay that way. Please come up with a fix, thanks.

The most beautiful UI I've seen for this kind of tool! But, why do not respect the regular screen resolutions or let user set own sizes? I have a 3440x1440 screen. I wanted set 2560px or 1920px width for example and it's not possible. Allow user to customize sizes should be the best, otherwise use common sizes seems to me logic.
