Thumbnails still aren't loading up quick enough for me, and the Info on the right takes a while to load up after. I have 51,601 games on mine that I run on i3 Windows 10 which might be why things kinda take a bit to get loaded up as I scroll on, search or even use Random Game. Speaking of the Random Game button, I still hope to see a quicker way to hit that instead of always going in via Tools for it.
I have yet to really try it all on my GPD Win, but hope to see that goes very well too.
