Sorry for the delay! I shared our OmniFocus roadmap at the beginning of the year:
We’ve just about finished delivering all the changes listed in the first paragraph, and will be turning our attention to global search in OmniFocus for Mac: it’s one of those “little points of friction” that I reference in the second paragraph.
(For now, it’s worth noting that the built-in workaround doesn’t require Pro: the Changed perspective is also available from the Perspectives menu in Standard. But I’m looking forward to that workaround becoming irrelevant.)
