I’ve never found Thunderbird search bad compared to alternatives, as long as I’m not looking to find content inside attachments. Really fast and responsive and being a desktop client without paginated results makes moving and deleting in bulk so much easier. Would love it to be as powerful as Voidtools Everything to get a bit more granular sometimes but otherwise pretty happy with it.
To the commenters justifying the written form MM-DD-YYYY on the basis of preferring to say the name of the month followed by the day (which the written numerical sequence does not preclude you from doing). If someone were to say something like “the time is a quarter to eleven” do you think they would have a case for writing it 45:10? And if so, how would you deal with the ambiguity of “ten past ten” if they wrote it 10:10 instead of 10:10?
