Wow, I didn't know that. So, it should be possible to write a differ. 
If *they* didn't already, that is...
Time to upgrade.

Of course its main purpose is to maintain several variants of one circuit board, but it's still useful if there is only one variant. With one simple menu you can show or hide all these components which will never be populated on the board (like the little caps that are there just in case the thing starts to oscillate). While hidden on the board, in the schematic they are still there, but they are crossed out. I like that feature a lot.

Sounds like what us software geeks call #ifdef, nice too :-)
