Maximum and minimum popup sizes when using Simple UI

[lucianopeixoto]

I've done some tests and found that using Simple UI, the optimal minimum and maximum sizes would be:

• Height: from 150 to 584 (after that it creates two scroll bars).
• Width 150 - 800 (after that, it doesn't really gets bigger).

Those number may only work for my configuration:

• Windows 10
• Resolution: 1920x1080
• Simple UI web interface
