Improvements to laying water pipes and power wires

I think there are some definite improvements to be made to laying water pipes (and by extension power lines, 'cause they seem to have the same issues) that would go a long way towards making it a much smoother experience and looking much neater. Allowing us to choose the input and output direction of the nodes, rather than assigning it (seemingly) randomly, would be great. This is especially problematic when you have multiple lines running to/from the same node. So a fix might be, you put down a node and then you're able to select a direction for the input/output and then lay the pipe. This would solve the messy node and pipe problem. To get your pipes straight and at perfect right angles or whatever you're going for, you currently need to set your pipe work, exit the game and restart. This makes the pipes straight (in most cases) but it breaks up gameplay and gets rather tedious if you're doing it multiple times over and over. So I think this fix might help to address that.
