Just saw you other thread...I DL'd the files, will take a look now.
****For that layout, your trace width is pretty much maxed out, the traces on the left side are as close together as they could be, any closer and home etching would run the risk of bridges between traces.
If you made the board bigger, then spread the components out, you'd still have to redraw the traces manually. you can drag components with their trace connections intact by pressing G over the component, but then you still have to redraw them because they'll overlap other traces. This is not simple tweaking, this is a major surgery, it's gonna take some hours. The only other option is to move the components to where you want them, then clear the traces completely and use the java autorouter feature, which works really well, I might add. The only problem with that is that it will only do two layer minimum, so it will route on the top layer as much as the bottom, meaning double sided home etch, which is still doable, but a few more steps.
So, ask yourself, do you NEED to do this? What's stopping you from etching it as is? Looks pretty good to me!
