Hmm, I made one double sided board with toner transfer (and said to myself to 
never do it again), because I use laserfilms and they have a great deformatin 
with heat. I used the holes (I first made the holes with my drill, then I 
transfered onde side and then the other). The board what big, it was about 2h 
a.m. and I had to show the board working at 8 a.m. and was not only the 
circuit, but firmware had to work too, and I didnt tested no one. Was a long 
night. Very long. Dont want to remeber :D
I tryed to make another double sided board some weeks ago, but using a board 
with photoresist in both sides. To do it, I made the holes again to fit on 
the two films, then I fixed them with clips and I placed the board inside, 
like an envelope. But didnt worked because my UV light was not good and I was 
tired, then I sended the board to the fab. At home I cant metalize the 
holes... someone knows how to do it?

Thats a good news. Because so, the program becomes WYSIWYG :D
I just need to redraw my parts... :)

IMHO, Lesstif is ugly yes. Well, I am very ugly too... and Xaw is ugly too.
I just think that Qt or GTK are visually much more attractive, themeable, 
etc...

Thats a good thing, I mean. 
Its good to have option, but I think how much problem is to have some 
duplicated (or triplicated, or more) work to make the same thing, i.e., to 
draw the GUI for the PCB core.
