Looks really cool. How do you simulate the permanence that paper laboratory notebooks have? I was always trained to write out everything, and if I ended up not using a particular procedure, striking it out so it was obvious it wasn't used but could be read by a third party whenever necessary (for legal reasons).<p>There's always the honor code, but my understanding was the lack of paper trail is one of the big issues with switching to computational means for keeping track of scientific results.
