Yep. I think I may actually do that. I’m leaning towards doing an extension for search to get all the emails into Elasticsearch or Meilisearch.

Cheers, yea its just something to work on/look into. I’ll never finish it of course, but if I can get a few versions into it and has some users/interest I’ll keep working on it.

Slint looks pretty cool. Has a very strong material UI feel to it.

Maybe a plugin would make more sense and reduce the scope a bit?

No offense taken. But I’ve made no assumptions on the simplicity, and I know its a big task and want to start small. I don’t mean to compete with Thunderbird, just I like it.

I think it would be a great exercise in learning the protocol and message handling.

Ideally I’d choose Rust because I enjoy working with it, but don’t have enough time to commit to it at the moment. But being Practical I’d probably say Java, its easy to get stuff going and has been around forever so it’s easy to find solutions etc.
