I am adding my cry of desperation to requests for a return of sort by tag. I have reverted to the legacy version in order to sort by tags in notes lists, and also organize tags themselves. I use Evernote as a massive repository for research that feeds various professional projects (consulting, writing) and have many uploaded documents, often simply uploaded and tagged in the moment for some later use. I do not remember all oWhoops. I am on a mac, not windows ... I will add this comment to that list.f my tags, but occasionally go in and organize/ cull.
Sorting a searched list by tags lets me quickly see the nuances and different connections between ideas, and find things serendipitously. A kind of dynamic mind map, or a search engine built specifically around my research needs. This is because I can search one term--which may be a tag, but might also be a topic buried in texts--and then sort by tags within the search results. The resulting groups of tags --easy to see because they are in alphabetical order, are a word-lover's version of a visualization tool--they show me the subsidiary ideas buried in the topic.
