I use Evernote to track action items. I use a saved search that shows me action items that I have completed in the past 7 days. I define completed as tagged with a tag that means completed. Because tagging a note does not modify the date modified for the note, in order to make this work i have to make a fake change to the action item note if for no other reason than to tweak the last modified date so that it will show up in my search. I'm sure you have users that appreciate the fact that tagging a note does not change its last modified date, but if it could be configurable to do so if desired, it would make a simple but much appreciated difference in my experience with the software. Thanks so much for making and improving Evernote. I am a huge fan and use it daily.
