3 forms at once + hierachy

I also began looking the prospect of having 3 or more forms at once. However I found that it made the code lag a lot, and i couldn't figure out how to improve it.

I think there is inevitably problems with my code not being the most efficient it could be, but it's hard for me to troubleshoot what could be better, but i am trying!

Here are a few different attempts at having 3 forms of the same size (each image is two different attempts at the code, i've just put them together in photoshop):

And in this trial, i tried to play with the hierarchy, and  have to forms the same size, and one larger. It didn't really work out to be very well composed or balanced.
