The current system is good as is, but I do see a few things that could or should need improving. To start with the optional feature, while I'm not suggesting having a huge list of waifus or something, it would be nice to be able to include both a waifu AND husbando. Now, the thing that needs changing, the search bar needs to be improved immensely. How it currently works is that only 4 characters pop up, but I've been trying to add KonoSuba's Aqua as my waifu and she literally will not pop up, because 4 other Aquas pop up instead. This is where the problem with the current system lies. It works well when you can actually simplify it with first and last names, but when it comes to names shared by multiple characters and you literally cannot simplify it any further, it becomes seemingly impossible to add certain characters. I think the best way to do it is include ALL results the moment you start the search, and then have a scroll bar so you can scroll through each and every one.
