Not very long ago I was in same situation as you. I needed single sided
boards. Beyond that, sometimes you need specific traces on specific side of
board. So how is that done? Read and experiment with layers and lines.
All objects, including traces have properties and layer is one of those
properties. In general, you can change properties at will, and you can move
traces around at will. For my single side boards I started with the rat's
nest and kept moving things around I had as few lines as possible crossing
each other. Using that positioning as a guide I then started introducing
traces until I was satisfied. Really is fun! A lot like a labyrinth
puzzle.
Autorouting created a mess, especially when you start to edit the autorouted
traces, because you now have to start paying attention to signal id
number's, etc being altered
