Add a way to add custom categories for your garage (like lists from the hot wheels app). For example I have my cars in different boxes (with labels) and I want to add custom categories for my cars in the app to match the boxes. I guess a filter based on the created categories would work.

Add a location; like bin, shelf, container, etc. So that stored cars can be more easily located. Though I love to display them all, there are some that make it to storage bins.

The ability to sort wish list and collection into folders where you can choose which folder to put a car in

Add list creation feature, so that we can divide our collection into categories

It would be cool to have an extra page on someone's profile where they can list about 20 or so of their favorite cars maybe also have lists by brand, "favorite Matchbox castings" "Favorite Hot wheels castings" "favorite Mini GT castings" etc... or just put an option to "add favorite" kind of like in Forza and those will be the top cars shown in a person's garage unless sorted otherwise.

A garage full of marked favorites from your collection.

Das man verschiedene Autos in verschiedene Galerien reintun kann damit man einen Überblick bekommt

For example if i only want to put Treasure hunts in one collection so it is easier to search for your cars from your collection
