Thanks for the prompt answer. You're right there is a search bar at the top, however it does not allow you to search inside each of the sets at the same time. That's also something that could be improved tbh. Either way, the search bar being present is not really pertinent to the suggestion. There's no real reason for the sets not to be sorted alphabetically, or at least have an option for it like the "SHOW EMPTY SETS" checkbox. I think it would be a valuable addition to a fairly outdated inventory UI.
