When coming up with lion designs, I tend to limit the number of breeding-only markings to make the design easier to accomplish. I also like to fill up all of the marking slots, usually, so when I'm left with one or two slots left that I'm having trouble filling, I use the Randomizer, and check the Custom and Event categories. Custom has just markings from the Marking Applicator in the Oasis, which is very nice. But Event has all event markings, including those from Celestial Raffle and event NCLs, so it's frustrating when I'm tempted by a look I like, only to scroll down and see that the marking is one I have to breed for after all.

I would appreciate it if there were an Applicator checkbox in the Randomizer settings. This would, quite simply, include all of the applicator markings, including Referral markings since they're now available in Gorilla Enclave. I'm not sure about the RMA-exclusive markings - they are technically applicator markings, but are far less reliable to get than other applicator markings.

As a side suggestion, maybe remove or split up the "Mutation/Referral" option? To be honest, it confuses me. There are no "Mutation" markings besides Rosettes, which are their own category, and it seems to be the place where many non-seasonal applicator markings live, such as Cheetah Royal, the Auburn and Ebony Feline markings, and the RMA-exclusive markings. There are also some seasonal NCL markings in there, such as Blue/Red Vitiligo 3/6 and Onyx/Blue/White Web from September NCLs.
