The title is meant to catch your eye, I'm not really suggesting that ;-)
I've made a post to the developers list on google groups but it appears to be stuck in moderation. If anyone could take a look at that I would appreciate it.
The post includes three suggestions for changes to future board versions. The one most likely to be of serious interest is removing the ceramic resonator on Uno/Mega boards (perhaps others too). By that I don't mean replacing it with a crystal, I mean getting rid of it entirely. I've done sample layouts for both Uno and Mega boards showing how this could be done. If you're interested either see my post on the developers list (if it ever gets moderated) or ask me more here.
