Logic Circuit Simulator 4+

Overall a great game, but:
Having a copy paste function would greatly improve the efficiency of building circuits, because now you have to put in gates individually and it’s kinda tedious. When I make a project I don’t really know what that project is gonna be about, I just fiddle till I get something cool, so when I name a project, I have no clue what it’s about till after it’s named and I can’t change it afterwards.
And when I try to move my camera/zoom I have to use 2 fingers. I’m fine with that, but when I zoom with gate/item In between my fingers, it spazzes out and moves randomly across the screen.
But other than that, it’s a great game.

The app itself works fine, but the gate menu sucks…a lot. Firstly, the menu should close with a back button instead of placing down a single gate and open with one button to cut down on time placing multiple gates. The fact that I have to tap a button near the top of the screen and then tap another one near the bottom is a real bother, since the wire tool has to be deselected just to place down a singular gate.
Also, I'd REALLY like if there were circuits you could save as boxes to save time when making the same stuff over and over.
Everything else works fine, but please consider improving user-friendliness so I can give this the 5-star rating it desires.

I need a way to build one circuit in a folder and be able to access it in another. So for example I could have a simple adder saved in one folder, link four of them together in another folder and name it 4-bit Adder. And make registers in another and link everything together in one folder to make a working computer. I was able to make what I wanted, but only after painstakingly making every part over and over and over. Please add this functionality without making us pay for it.
