Allow user control of the display size of the game icons/title
By default, the Twitch windows desktop app displays the My Games icons quite large. For a small number of games this may be fine, but for my 111 game library, it requires more scrolling than I'd prefer. On my 1920x1080 desktop, with the Twitch window slightly smaller than full screen, my game matrix is 9 wide by 3 rows. It appears I could fit 10 across if I made the window larger, but I have reasons for not doing so. I would like to see more of my library at a glance without scrolling.
I would suggest either a zoom option to scale the icons and game title beneath to a smaller size that I'd prefer, or a fixed selection of small, medium, large, if the flexibility of zoom is too difficult to implement. I would consider the current default to be "large" icons, but some vision impaired might actually like another larger option.
