Previously, I was able to sort the email messages in my inbox by DATE, or alternatively, by Subject, or by Sender. Now, they appear NOT in date sequence, but mixed together with other related emails by "THREADS". It makes it very difficult to identify NEW emails and respond to them promptly, or for that matter, not miss them entirely.

I wish to sort by DATE, and sometimes sort on the other columns (e.g., Subject, or From columns), but in all cases, I do NOT want them to be linked by "thread". But, I do NOT want to have to disable the threads individually. I just want to turn "threads" off completely.
