4 months ago I would love this feature! Batocera's emulationstation has a similar feature, I believe it's called Dynamic Game Lists. It's similar to how genre lists are made but the user can specific any search term or metadata requirements. The way Batocera handles it is all the Dynamic Lists are in one group (like a system) and each one can be anything; for example all final fantasy games on all systems, or all nes games from 1994, etc. These are auto updated whenever new roms are added too (the dynamic part). I disappointed recently to learn that not all emulationstation builds have this feature and seems Batocera team added it in their build (ES-DE doesn't have it along with other missing features).
Similar to the feature that separate games if they're newly added, favorite or recently played but let the user use it's own criteria to create groups. Like a "Franchise group" or "completed games". And if they share their devices with someone then "X person videogames" so the other person can easily find the complete list of videogames they play.
I was thinking of something like creating a personalized genre of videogame would be an easy way to implement this feature.
