Using your own tags as an example, if instead of using nested tags as you did, you created the following tags: Wine.CellarRed Wine.CellarWhite Wine.DrunkRed Wine.DrunkWhite In a new wine-related note, when you go to the tag field and start typing 'Wine', you get a drop down list of all your tags that begin with 'Wine'. That's what JMichael is doing with his SYM.<symbol> tagging. So his list looks something like: SYM.aapl SYM.msft SYM.intc SYM.goog And if your list of such tags is long and cluttering up your tag list, you can nest them all in a 'MyWines' or similar tag. But that's the problem , why would one want to start typing wine? Just select wine from a list your top level nested tags so much easier. and then select say Cellar white, works quickly on Android and Windows PC I do think tags are great by the way!!
