It provides screenshots, categories and icons for Flatpak packages. AFAIK those aren't provided by AUR or the official Arch repositories. Icons seem to be integrated for some official packages at least.
A Shelly in-built way for user contributed additional data for Arch packages could be a way to tackle this. But that needs additional infrastructure, developers and volunteers who curate the contributions.
Shelly is a nice frontend. Octopi is too, to quickly check PKGBUILDs, show contained files or open the respective AUR page.
Yeah not eating enough protein does that. Try TVP. It's an extremely versatile (Chilli, Lasagne, meatloaf, meat balls, bolognese, Asian fried noodles etc.) and cheap (for now) replacement for ground beef. It seems to have a better amino acid profile than chicken:
Chicken: https://www.researchgate.net/figure/Total-amino-acids-and-amino-acid-content-g-100-g-meat_tbl1_338348672
TVP: https://www.admanimalnutrition.com/webcenter/content/conn/WCC1/uuid/dDocName%3ATVPSPECSHEET
It blows chicken out of the water regarding minerals like iron, magnesium or calcium. Compare the TVP-spec-sheet with this. Tofu (if made with gypsum as a coagulant) is even more packed with calcium, where 100g can already mean more than 1/2 of your daily needs.
Chicken comes with more vitamins (but also antibiotically resistant bacteria, chloride, growth hormones and animal suffering), while TVP brings anti-oxidants in the form of isoflavinoids.
Yeah it's based on soybeans but you can see tons of manly man vegan body builders eating that stuff on a daily basis. They got big breasts but those are not from phythoestrogens.
Regarding your Burger addiction. TVP is the perfect remedy.
A quadrillion of websites exist for fire vegan recipes (which take care of the vitamins missing with TVP) with one of the most prolific one being https://www.noracooks.com/.
