I'm a religous Evernote user, across multiple platforms. This note applies to multiple ones, but specifically happens in Windows. There's a very specific "feature" which is really painful. - Make a new note - Go to the tag area and misspell a tag, such as "ChecklisK" [sic] - Delete the tag BEFORE SAVING THE NOTE - Type the correct tag "Checklist" - You will notice that you have kindly (URGH!!) created the misspelled tag in my tag list. And what's worse and a reminder of this painful feature, you will kindly (URGH!!!) offer to help me misspell it again (along with the correct spelling) when I type "Check..." the next time I'm tagging. You have to manually delete the unintended tag from the list. Please don't save new tags created and promptly deleted - I'll bet $10 your answer is "Ah, yes, but we save notes for you automatically, it's a feature!". You're right and that's one of the wonderful things about Evernote. Except in this case! Apply some intelligence here and delete the tag. How about this simple heuristic: If a tag is created and has a lifetime less than X seconds in the note that created it (you pick X...10 seconds would be fine!) then imagine that never happened as it was clearly unintended.
