honestly this is a great mod, and the only things I could even remotely suggest is make both small version and large version logic gates, and to make the covers dyeable for easy identification. both would create a highly optimized experience and would be source for Mojang to emulate in a future patch.

We now have an add-on mod called Tiny Gates! https://www.curseforge.com/minecraft/mc-mods/tiny-gates
This covers the small versions of common logic gates request.
Next step is to provide blueprints for larger gates.

Thanks for the suggestions.

The covers are already dyeable. They take on the color of the panel. Right clicking with a dye changes the color.

There are plans for an add-on mod to provide tiny logic gates. I hadn't planned on providing large logic gates for a couple reasons. One, you can build logic gates with the circuits, and two, there are already several mods that provide them. One idea I've been considering is providing craftable blueprints for commonly used circuits and gates.

Changed the title so I can see, at a glance, what's on my todo list. Removed the reference to dyeable covers since we already have them. If you meant something else by that, please open a new issue for it.
