In general, something like that would probably be taken as a feature request anyways if it was the main subject of a topic. One correction. There's no such thing as a tag created under a notebook. Tags are wholly independent of notebooks, and can be applied to any note in your account. This is generally taken to be a Good Thing, since it makes more flexible organization schemes possible in Evernote.On the separate topic of displaying tags when a notebook is selected, I think that the UI should have better ways of portraying that. The 4.x Windows clients were explicit about that in the tag tree; the 5.x series dropped that, but you can get a list (not a tree) of tags available in a notebook by using the search control that's at the head of the note list: select a notebook in the notebook selector at the left, and then click on the tag icon on the right, and a dropdown list of available tags should appear. Initially that list will contain all of your tags, but click elsewhere in the control, and the list will disappear, and the text "Click to filter by tag..." should appear. Click on that, and a list of tags, appropriate to the selected notebook, should appear. Select one, and the note list will of course be filtered by that tag, you should get a new "Click to filter by tag...", and if you click that, you should nw see a list of tags that's appropriate to the current filtered note list. And so on. This is kind of awkward, and has the feel of a work-in-progress, but it generally works. In general, the Evernote clients don't use a lot of special flags for special behaviors. I think that the UI could still use more work. Tag organization is a topic unto itself. I consciously use few notebooks, and tend to create only general tags that can be applied anywhere, in combination with others. I don't have a lot of tags, so it's not hard to remember what they are. Simple tags plus a little text search generally serve well at isolating a small set of notes that make finding the one(s) that I want easy, but everyone's use case is different. My idea is to keep things as simple as possible, and spend more time with my notes than fussing with their organization. I used to sum it up like "Use notebooks where you must (sharing, local notebooks, offline notebooks) and use tags for everything else", but I think it's actually closer to "Use notebooks where you must (sharing, local notebooks, offline notebooks) and use tags when you need persistent organization, and use text search for everything else". I know there is no such thing as a tag created under a notebook, that is my point, it would great to have them, but by the sounds of it I will have to use your approach of using fewer, more general tags. Personally I think that's a pity. Thanks for the feedback.
