Feature Idea

How about something that would allow me to flag a particular post for follow up or reference later.   Kinda like outlook or an email program.  There are lot of posts that I would like to read in greater detail; require more time and thought to reply to than I have at the moment; save in my training log for reference (kinda like tri-archer's how to shave post); etc.  Maybe this exists already and I have missed it, but I would find it useful, especially since I browse threads from multiple computers and devices. 

From the business angle, p?erhaps you could have the flagged thread ?o?p?e?n? ??i?n? a??? ??d?i?f?f?e?r?e?n?t? ?w?i?n?d?o?w? ?t?h?a?t? ?h?a?s? ?s?o?m?e? ?c?o?n?t?e?x?t? ?s?e?n?s?i?t?i?v?e? ?a??d?s? ?o?r? ?s??o?m?e?t?h?i??n?g?.?.?.?
