Our small business has been evaluating EN for Business as an alternative to Dropbox. EN has the advantage of handling more file types more easily, better searching, tags, etc., but Dropbox, which we use now, has the clear advantage when it comes to organization. We need to be able to organize our information at least one more level than EN seems to allow. As an example, our company develops formulations, each of which has many associated files and documents. Within EN we'd love to be able to create a folder called "Formulations" and then within this folder create a notebook for each formulation. Each formulation notebook could then contain all the associated documents for the formulation. As it stands now, each formulation is a notebook, all of which appear at the same level as every other notebook within the "Business Library" view. With hundreds of these, it gets cluttered. Stacks are close, but they can't be shared. Stacks I create on my Mac don't appear in the Business notebook and vice versa. I'm also concerned about the limitation of the number of notebooks, 250 I think, which is far too small for our use. It would be great if EN had the ability to create some kind of organizational hierarchy beyond the klutzy and limited stack concept. Why not replace stacks with "Folders" or that could be shared and capable of handling thousands of notebooks each? Something like: Business Library - Formulation Folder - Formulation notebook 1 - Formulation notebook 2 - Formulation notebook ... - Client Folder - Client notebook 1 - Client notebook 2 - Client notebook ... - Presentation Folder ... I understand that much of this can be accomplished with tags, but that's a hit or miss workaround when groups of people are expected to maintain a tagging system. Thanks.
