I have a comment about line width.  Sometimes you want to create an 
invisible
line.  To me, it seems that specifying a line width of 0 is the best way 
to do this.
It is possible to use lines that are the same color as the background, 
but that is
more of a hack because if you change diagram colors, it breaks.
In dia, a line width of zero is a 'hairline'.  A user should be able to 
create
hairlines simply by using a small width.

I am working on line decoration code that should make it easy to specify 
names
as well as 'bus-width/number-of-wires' slashes that stay centered on the 
line.  I'm a
bit busy, so it will be a few weeks before I can get out a 
semi-user-friendly version, but the
code is mostly written and works well.  This same decoration code will 
make it
possible to create clock-input lines that can be stuck on flip-flops, or 
(NOT) bubbles
that can be added to any gate input.  I might be able to hack the code 
so that decorated
lines can be stuck together with fixed user-specified angles.  Stay tuned.
