Feature: Adding a filter search bar

[sodes-proxy]

Hi!

First I want to say that I'm a big fan of the tool, been using it since persona 5. But recently I may have gotten lazier because when I was checking the new nahobino skills from SMTV:V trying to min max my build, it occurred to me that a filter search bar would be really helpful, I know that we can ctrl + F to find whatever skills I'm interested, but I think it could be an awesome feature especially for mobile users.
