I hear you. It was nice to have all the APIs and user guides “sealed” together into the devlibrary URL. What I’ve done is downloaded every single API and DG zip file onto a folder on my core development machine (actually we clone multiple development images and run everything in VM but that’s another story) - and then create a Firefox bookmark folder that contains all the index.html or default.html bookmarks for each guide, and then fire up Firefox and it preloads every link - bam bam bam - and voila!
