Pressing 'R' while dragging underground pipes places a regular pipe and then an underground pipe in the direction of the cursor.

(If a new underground pipe was already started it is replaced by a regular pipe.)

I like this
Would probably break some mods though.

it is an extension to improved belt building, which was introduced before the release 1.0
I think the idea is properly presented, so we would find the implementation in the planed DLC expansion.
Perhaps make it as the free part of the paid DLC would be smart.

I highly recommend this mod

Definitely a +1 from me!

+1

Similarly a +1, with space age and the smart belt tool, pipes seems quite behind in terms of QoL (having to manually switch between regular and underground is not smooth) and would greatly benefit from this change. I would have create the same forum post if it did not already exist.
