Could the application be fixed so HiDPi screens work well with it? The text and game icons are very small on a HiDPi screen. I’m assuming it’s possible, as many other apps are starting to update their ability to accept scaling factors (QT5, etc).
I second this.
For the images, we have plans for providing bigger banners and icons.
The text should be handled by Gtk itself and should already be HiDPI compatible.
