> How do you do Gmail style threading view in thunderbird ? They changed the game wrt email display and 20 years later I still don’t know how to get thunderbird to do it.

I hate it. It hides texts, and I lost answers in this view more often than I want to admit. If it is not ping-pong conversation (I wrote you, you answer, I answer at your last answer, etc), but discussion between 3+ people where different people answer to different messages, gmail view is total mess when you cannot understand who answer to what. As I said, it doesn't support threads, only messenger-like conversations.

Any e-mail client which doesn't support tree view for threads is wrong.

You can put answers to same folder that message your answer in (any?) sane e-mail client, Thunderbird is not exclusion.

Update:

> smart hiding of quoted text so you only see new content

I've missed text hidden by mistake due to some formatting quirks more than once. It is solution in search of problem: proper quoting doesn't need any magic.
