Add a second search field spesifically for scryfall filters, that doesn’t clear when you clear the normal search box (the actual search query sent out would simply be one appended to the other). For example, if I am building a deck, and I want to search only for blue cards, I could set it to color:U. Then even when I clear my search with / to enter in another card name or go back to the main deck view, it will stay there next time I want to search for another card. This would make it faster to do many searches following the same filters.
A profile setting could also be created for a default filter, so you can have a filter apply automatically to every new deck or search you create. A use for this could be always searching for only cards legal in your preferred format, or defaulting to search only for foils, non foils, -is:covered, among other things.
I think this would be pretty useful in many situations and make searching faster in general.
