Yeah, except for the fact that you can clip notes into a notebook automatically, i.e., select the notebook you want, clip away, and they all go into the right place. Even with a decent tag hierarchy, I would have to remember to tag my notes after clipping
The additional feature that is needed to make the whole issue of organization more efficient would be automatic tagging similar to EN 2.2 which could "assign filters to any category, effectively turning it into an Auto Category."
But that is only the efficiency issue of getting things tagged. This, combined with the ability to have a Tag hierarchy when desired, would be truly a huge improvement.
There are several things that make the various flavors of Evernote great: Clipping (in both, but EN3 is more flexible); synchronizing to the web (EN3), searching (EN3 is a bit better); Categories (EN2.2); AutoCategories and filters to create them (EN2.2).
To maintain its greatness, Evernote needs to get these all working together. Tons of clips and notes that can't be organized the way we think isn't the best solution to information overload. And we all work and think differently. Evernote needs to be flexible enough to support a larger group.
Maybe Evernote 4.
