I think I know a good first step in tweaks to the DoM website: Changing all the download links in the Gallery to look more like buttons. Not, y'know, actually make them buttons, but use CSS trickery to make them biglier and more rectanglier, easier to click/tap.
Also, that'll give me a chance to consolidate the multiple sizes of wallpapers down to just one per aspect ratio. Which in turn will also give 4K-ish 16:10 wallpapers, despite such monitors being stupidly rare and/or expensive.
