When using fullscreen you can have a second screen, but:
1- if you click anything on second screen it minimizes Eldevin client.
2- Eldevin can only run while full screen on main screen and cant be moved to second on need.
3- anything you do that would open a windows menu or ctrl-shit-esc will make client minimize.
so this way i cant play Fallensword and Eldevin at the same time lol
