Hi Chad,

I've given it some more thought, and I still think that the current 
situation is somewhat inconsistent in two respects:

- Through-hole connections can be fully embedded in copper with one 
mouse click (thermal function), and that doesn't present DRC problems. I 
think it would be handy to have the same option for SMD pads (which now 
require rather more laborious solutions to achieve the same result). 
IIRC, thermal lines for SMD pads were rather difficult to implement, but 
solid copper should be easier.

- Short circuits are currently not flagged by DRC, but only by pressing 
'O' (optimizing rat's nest) -- while I'd say that an unintended short is 
certainly a design rule violation. I have in fact been bitten by this 
arguably Very Bad error, when I made some last-minute changes, performed 
a DRC, but forgot to also check with 'O'.

Regards,

Richard
