Thank you for your quick response. However, I think we're talking about different things: When I go to About Evernote (I'm using the Windows version) I'm told it's version 10-7-6. You reference 10-8-4. Is that maybe for another platform? Or do you have access to a version not yet available to the general public? Evernote says my version is the latest generally available.
I did discover the main tags menu, however. I used to be able to just click and drag. Now I have to laboriously move them one by one. It's actually LESS efficient. And I see the "minus" search and the "plus" search are done in different areas. This is a step BACKWARDS. The two features I used most now come with extra steps.
