I process my email inside DTPO. In Mail I delete and remove the obvious stuff that I do not want in DTPO, then I import everything into my “+Inbox” group. The next step is creating replicas of everything new in a group called “+Reference|Communication|Email”.
Then I start processing my Inbox. Often the copy in “Reference Material” is enough / the mail is not related to an ongoing project. In that case I delete it from the Inbox, knowing that an archived replica in the reference section will surface whenever I search for it.
Now to my feedback: When I hit the delete key or button in the toolbar the selection / focus is lost (in the Mail-like view available in DTPO). That is a minor annoyance. I would appreciate if instead the next or previous entry would be selected.
