Right now, only null cells are available when working on ic blueprints (1.7.10 versions did have all 3). It would be really handy to have the buffer/invert cells for building ic circuits like 4-16 decoders, 7/16 seg display drivers, binary to decimal converters (think double-dabble). Those are not possible to do in an ic with only null cells, and would require massive real estate on a blueprint if done the 'hard' way with not/buffer gates, never mind the wiring mess. It would be amazing to see and/data cells as well...those are really handy for latching data while keeping things compact.

This is something that is planned, due to the complexity of how integration 'compiles' the logic down, i'm not sure if the backend currently supports this, @MrTJP was working on it, and got null cells working. He will have to fill in more.

+1 This would allow you to design any kind of decoder in an IC. Imagine being able to fit a 4:16 demultiplexer in a single block. The massive 256-address Memory Address Decoder I recently finished would fit in just a few blocks!

Is you still planning on implementing this?
It would be very useful to have.
