Question: if one were to reimagine an email client for today, what would it look like?

For me:

- I don't want to pay a monthly subscription (but I will pay for software)

- Semantic search ("What's the confirmation number for my flight next week?")

- Automatic categorizing and tagging based on my behavior (I hate doing this manually myself and taking an "action" for every single incoming email.)

- Lightweight (memory/CPU), fast

- Everything is cached and available locally, including search

- A better UI for long meandering threads: today I just get completely lost, especially when some people on the thread use outlook and others use gmail

- Information dense

- Calendar sync: view all events I've had with a person
