Oh, I just tried it, looks neat but qview has a bit different philosophy from imv (for tiling), shortcut bug (can't remap F key, even after unmapping it from any else action), and what is really bad, there are viewing issues on sway. For sake of justise, I tried many viewers but unfortunatelly imv "just works" better than everything else for me. So I use mpv, web browser or kitten icat (viewing images in kitty terminal) for webp. However, I will use qview on Windows, thanks.
For sure! Compared to jpg it's still better for sharing pics online, but honestly Avif files are even smaller than webp at the same quality. I usually prefer WebP (for sharing) though, since it’s more widely supported.
I'm not that old linux user so it's a bit interesting for me, when Windows 7 was closing, linux community was also so excited and offered everyone to switch to linux?
