Hi! Since there is an option to select how many channels to combine into a composite number, why don't add an option similar to that to all logic gates (select how many inputs you want).
In the micro controller edditor you also have 2 Boolean function blocks. 1 with 4 inputs (x, y, x, w) and one with 8. That way you don't even need a logic chain + you can make it a lot more complex with a lot less space
