This is why I'm canceling my Evernote subscription on March 23. Without tag sorting, Evernote is useless to me. Tags are not even a second class citizen right now.
Tag management in the v10 client is unusable when you have a large number of tags. At the very least, they need to bring that feature back. I just went through and fixed my tag nesting order with Legacy, because that isn't going to be possible next month.
It's not just GTD that requires tag sorting. There are so many other workflows. Evernote's insistence that they know what's best for us is taking away it's universal ability to support other workflows. It's stifling, condescending and frustrating to lose something that's been so useful for so long.
See you later Evernote. It'd been fun while it lasted.
