I've just done a good ol' Google search to try to learn how nest my Evernote stacks. I've found blogs calling for EN to add this feature, blogs helping folks cope with the lack of this feature, and blogs trying to help people adapt to tagging as a clunky replacement for hierarchical organisation, and I've found this thread, which began in 2008, of which I've read the first three pages and this last page. Here's my question: after six long years of people consistently asking for this feature, is there any place where EN has explained their philosophy of leaving only one level for notebook stacks? I'm simply curious as to the reasoning (and could probably learn from the read). Even gMail has allowed users to create the comforting appearance of subfolders by providing for nested labels.
