You got my vote for RA2 Wizard. Always and forever.
the eye mostly. but what helps is to zoom in while in the chassis tab then switch back to the components tab, and without touching the black square, go pick out your component. once you click attach, you can then go in the black square without it zooming out.
but how do you allign the ruler in the start? lol
Send it to click, it might be good for DSL 3.
