I am astonished that since this was first noted as a needed added feature (2014), nothing has been done, or commented on from Evernote at all. As a result we have in hand today with Evernote (a great product) a single item/document experience. No one in a business environment works this way. Surely someone on the Evernote team has a response??
Adding another voice to the ability to "sharing a stack". Being able to fold several small notebooks (ie: stacking) under the umbrella of a single stack allows for organizational cleanliness. Unless there is a better' way, creating a 'stack' brings them together. Would make sense to be able to pass this organization onto the shared person or group. Am I missing something, and there is indeed a better way to do this?
