I recently upgraded to Ubuntu 12.04 LTS, which updated gEDA.  Everything 
works well except a couple of minor annoyances.  I may be doing 
something wrong.  Here are my questions:

1.  I tried to change the default rat thickness in PCB by including the 
line 'rat-thickness = 2' in the file '~/.pcb/preferences', according to 
the online documentation (which may be out of date?).  This works as 
expected the first time I start PCB after that file edit, but when I 
quit PCB, that line seems to disappear!  If I don't re-edit 
'~/.pcb/prefernces', next time I start PCB the rats have their default 
thickness.

2.  In the version of PCB that came with Ubuntu 11.11, traces were not 
transparent if I remember correctly, so the trace of the active layer 
was in the foreground.  Is there any way to revert to that behavior in 
the PCB version which came with the upgrade to  Ubuntu 12.04 LTS?

3. Is there any documentation on how the 'Import Schematics' option works?

4. If the new PCB has 1nm resolution, as has been discussed on this 
board, I don't see it.  The finest grid available as an option is only 
0.01mm, just like before the upgrade to Ubuntu 12.04 LTS.  Am I missing 
something?
