In "other" CAD software I typically keep a list of possible components to use during the design phase. Could be part numbers and web links to mcmaster, grainger, Digikey etc. Or possibly more design type stuff like a list of Coeficcient of Friction, tap charts etc. I would love to see hyperlinks work in the comments. Right now i have tried to make it work but it only selects the comment box to "orient the view". You can't even copy/paste text from the comment.
