Ok, so here's my solution for now. My understanding from reading various posts in the forums is that Evernote 10 is missing a lot functionality that the earlier version had. Really too bad, but that's where we are. I'm guessing that the functionality I'm looking for here is one of the things that is missing. At the moment, I've installed a legacy version of Evernote along with Evernote 10, which can apparently run side by side on the same machine. That lets me use the features I miss having for now. Hopefully things will be updated soon. Hope this is helpful to others!
