Include outbound (my replies) emails in "newest" sort in personal inbox

Today's Options:

• The "newest" sorting allows users to always get the latest email on top, but outbound emails (my replies) are excluded from being considered "new".

• My replies do appear on top on the "newest unreplied" sorting, but then I don't get the newest emails on top.

Feature Request:

If I reply to an email, then I want that email to be on top of my list of emails (the feed). Suggestion for a hybrid of the current 2 options and consider the outbound emails (my replies) as "new" too.
