With most programs and apps, I can move floaters off to my second screen, but EasyEDA seems hard coded to keep them within the main screen. I assume this is because it is based on a browser engine so I accept it's not a simple task but could these windows be made to launch in separate browser windows and hence be relocatable to another screen ?
Also once you've done that, migrating the left and right menus should also be possible. Also then create a user definable floater with all the things so we can put all the things we use most on it rather than using hotkeys.
Not an easy task I agree but maybe give it some thought ?
