TL;DR/What
I would suggest to add the same overlay that appears on fluid pipes to highlight the segments that are connected to them on heat pipes.Why?
It would be way easier to design or debug complex heat pipe networks on Aquilo and I think it would be a nice QoL change.Storytime
I was playing with my friends and we were mucking about on Aquilo trying to figure out how to transition from basic setups to stable science production and an issue we've encountered is that we had made two separate heat pipe networks working in parallel by accident (one connected to some nuclear reactors and the other fed by solid fuel production) and when the solid fuel one dried up, everything that was connected to that network froze over and we had to spend some time fixing the issue, which is not the end of the world obviously, but it would have been instantly noticeable before the freezing happened if there was the same overlay for connected heat pipe networks that there is for fluid pipes.A bit later, we decided that the separate network was a feature and not a bug, so that we could have a backup in case the major network fueled by the nuclear reactors failed for some reason and we now have the opposite problem: making sure that the network stayed separate and not connected by accident is a bit harder than it would be if there was the overlay.
