So far absolutely loving the newest update. Still would like to see search... done in a couple of ways (either both or at least one):
• Search in the body of a message: simple search where a term can be highlighted. Would be great if this could be set so it "follows" whenever you open a new message. Say I am looking for messages with the term "Linux" or my name or some other term -- view a message and it is already highlighted on that message in each of the places it is found, maybe with arrows to go previous and next on the search term (and if the term does not show up the search field is a different color). In Thunderbird it is red if the term is not found, white if it is.
• Saved searches: searches where you can set up a criteria and they auto-populate, perhaps with a number next to them to indicate the items found. That way you can set up a search for, again, say the term "Linux", in a specific group, and unread. This allows you to see those terms very quickly. These searches could be saved on the side, like Smart Folders in the Finder or in Mail.
I assume the first is easier than the second, but either would be great -- both would be amazing.
