Zoom feature. CTRL & +/- , CTRL + Mousewheel. People have been asking for this on Steam for almost a decade now. Resolutions keep getting higher and I'm not getting any younger.

For now, I open any Steam or GOG forums in Firefox but if you want me to actually use your client you should probably add this function.

The best forum for Galaxy discussion is https://www.gog.com/forum/general_beta_gog_galaxy_2.0

You can also make a wishlist entry https://www.gog.com/wishlist/galaxy

Sending feature requests in the general discussion forum isn't that good of a way to get your voice out there.

EDIT: It looks like someone made a wishlist item for this feature already, so give your votes:
