I follow GTD with Evernote. The people at Tonic had a great tutorial years ago and called it the secret weapon (for Getting Things Done). Anyways... sorting by tags is crucial. It's how I can sort all of my notes @Work and 1-Now as when it's due. Then the 2-Next tagged tasks would follow, with 3-Soon, you get the idea. I need sorting by tags. I pay for Evernote and I feel like a feature I was paying for has been removed without warning.
I need to know when this feature will be restored, or if it's not in your product roadmap to restore it so I can evaluate other note/task software.
