I noticed that under "Recent Replies" all of the subject lines now begin with the words "Response to...." Personally, I find this distracting because it makes it a bit harder to scan the subject lines quickly. I think I understand why this was added but I find it counterproductive. What would be ideal is if there were a way the words "Response to" could be disabled as a settings preference. If that's not possible (and my guess is that it isn't) then I'd vote for removing those words in the interest of quick visual scanning of the subject lines.
Thanks for considering this suggestion, whatever you decide to do! Much appreciated.
