Maybe it works great on a 20+in screen! But I do not have a 20+in screen, I have a 15.5in screen and GSL does not play with that AT ALL unless it's zoomed out to 50% (at which point it is impossible for me to read.)
GSL at 50% zoom vs GSL at 100% zoom
As you can see, when the GSL is zoomed in to 100%, all the small frames break, with their contents either shoved off to the side or just cut off entirely.
