Mike, are you from the Evernote team? You should say so, if you are.
Seems you're more interested in defensive posting, i.e. defending the app.
My objective here is to improve the app, not criticize it.
I've been using this service for a decade. It's an amazing app. I recommend it to everyone.
You probably missed two important words in the title of this thread: HEAVY USERS.
There's no question that Evernote can do a good job of searching tags if you keep your tags short and few. But heavy users do heavy searching and heavy note-taking. And yes, sometimes heavy users need to have slightly longer tags. That's the nature of a heavy user's work.
I'm just trying to convey to Evernote developers that you need to grow with the needs of heavy users. And I've pointed out a couple of issues to alert you. That's all.
And, Mike, if you're a member of Evernote team, you're not doing a good job of promoting the app by trying to suppress helpful points that I'm trying to convey.
And, if you're not EN team, then I thank you for your useful input, but it doesn't address my point.
