I, too, vote for tag inheritance. In the meantime, here's a trick I've come up with for tagging multiple items with multiple tags. Say you have tag="Red Sox" and subtags "Ortiz" and "Varitek." Now, if you have created a bunch of notes tagged with Ortiz and/or Varitek, they will not have inherited the parent tag "Red Sox." Here's how you can quickly tag them all Red Sox. First, select any one of the notes tagged with Ortiz and/or Varitek and tag it with "Red Sox." Then select all the Ortiz and/or Varitek notes with the select all (using Ctrl+click, search + select all, or whatever method). Now click on "Tags" (or use kbd shortcut). When the tags box pops up, you will see that any tag that applies to *all* the selected notes will have a check mark. But any tag that applies to only *some* of the notes--such as "Red Sox" in this case--will instead have a box filled in with green shading. Now, if you click the box next to "Red Sox," the shading will turn to a checkmark, and "Red Sox" will be applied to all the selected notes. This is a helpful trick in some other instances, such as when I'm working on a certain topic and quickly clip a whole bunch of notes. I tag the first note right when I clip it, then, when I'm done with the topic, I go in and use this trick to extend the original tag(s) to all the relevant new notes. It's just a workaround, but I find it useful on many occasions. Also, my description is based on the Windows application. Not sure if/how it can be used on other platforms. Happy New Year.
