Components count limits

Hi, I have a question, how many components can I add to designer space?

My breadboard:

https://www.circuito.io/app?components=7950,9442,11061,11824,13959,13959,13959,13959,13959,250754,250754,250754,748665,821989,975601,1234567,2345678

I’m asking because I need to add additionally 3 A2212 motors and 3 ultrasonic sensors, but when I try to do that I only see loading ring and nothing more.

You can only add 10 inputs! Thanks for the question!
