I don’t want to be a party-pooper here, but I think tagging is one of Evernote’s biggest shortcomings. Maybe it’s just the way I work, but I always find tagging notes a teethgrindingly annoying experience. Just for reference, I tend to drop a lot of notes into Evernote at once and then add the tags afterwards. This often involves trying to add multiple tags to notes, or single tags to multiple notes. A few examples of the things i find irritating:

1: How to avoid the over-tenacious autocomplete?

Example: I’m trying to tag a document with the [new] tag “mot”. I already have several tags beginning with the letters “mot”. So as soon as i type “mot…” Evernote tries to autocomplete it to “motoring”. If I hit return after typing “mot” I get it autocompleted to “motoring”. If I type “mot” followed immediately by a comma and then hit return [which I'd expect to tell Evernote to end that tag there] it also gets autocompleted to “motoring”. If I type “mot” followed immediately by a space and then return, the tag does not get created at all.

Suggestion: Use the right arrow key, or tab key to accept an autocompletion, as most word-processors do, rather than forcing autocomplete.

2: tagging multiple notes or multiple tagging notes

If I select multiple notes, I can drag a tag from the tags panel onto those notes, to apply the tag to all those notes at once… or do it by dragging the selected notes onto a tag in the tags panel. All well and good. However adding multiple tags to a note [or notes] is a major PITA:

A: I can’t select multiple tags in the tags panel to drag onto a note [or notes] for, as soon as I click on one of the tags, then the notes panel is automatically filtered to show only notes already having that tag. Similarly, selecting a bunch of notes and then trying to use the “Tags” popup at the top of the window just filters notes by that tag. People might ask “What’s the problem with just dragging the tags you need one after the other onto the selected notes?’” [or vice versa], but when you have several hundred tags, it becomes extremely tiresome scrolling up and down the list of tags trying to find the ones you want to add to the selected notes.

Suggestion: Provide an easy method for applying multiple tags to a selected bunch of notes at once.

Disclaimer: I’m pretty new to Evernote –only been using it for about a month, so apologies if any of my abovementioned problems are due to user error and failure to RTFM!
