The lesstif GUI has a minimalist layout in order to maximize the amount of screen real estate that goes to the layout window. Is there a true reason this is not done in the GTK+ GUI? - I wrote 3-4 GUI programs so far from Microsoft foundation classes to raw X11 to GTK+ to FLTK and always

Is it correct, that round linestyle is default because of its superior mechanical/thermal properties? - I definitely read this for pads and it's easy to imagine, that a corner more easily delaminates than a round edge. In the light of this, a small bend corner style would be cool ;-) Peter

Not because of the bugs I ran into but since choosing a footprint is a difficult process in it self I was longing for a footprint browser. The easiest place to start a clean implementation may be gattrib, that I found conventient to duplicate footprint choices, once one has been assigned gschem.
