Evernote promised rapid improvements once they released 3.5 for Windows, and they are starting to deliver. I just installed the latest Beta, 3.5.2 Beta 2 and it adds draggable tags. I've been waiting for that. I have a lot of tags, and often I forget the one I have and end up creating new tags. For example I have both "google voice" and "google_voice". Now I can see my list, and drag the appropriate one over.
Guess I need to clean up my tags now.
