I just found this application and this is very useful for my future academic projects!

I was hoping that you can add 7447 IC because I was attempting to create a 4 bit adder and sub then I realized that there's no 7447 IC.

While tinkering around the application, is it possible to add a function where you can have multiple presses? Like, I want to press button 1 and 5 at the same time and is there any way to add a search bar function so you don't have to click every category of each component?
