Good afternoon!

My suggestion is to return option that was in the past: search kings by owner's name.

Why? Because some people search "clean" lions and some people search "g1" lions. Owners usually have this mentioned in their nickname. It was really useful for me, as I breed mine lionesses only to G1 studs. I don't want to check heritage of every lion. I guess many people think so, maybe not about g1, but about clean studs. There is no option to search for studs with specific heritage criteria. I think it's hard to make such options! But search by nickname was existed, I think it won't be a serious problem to return. It will make stud search easier!

Do you support? ^^

P.S. I don't know why we don't have this option now!

Sorry, I'm not so good in English, and Myriad (#76) described it much better!
