It's okay, but the shortcuts don't work and the options for specific sizes are very limited. there's also not support for multiple monitors

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.
