Some people talk about mailing lists with a lot of reverence, but I have only ever found them to be extremely ugly and unreadable.
Are there any good clients out there that make them readable? For example a lemmy-like, threaded interface with interactivity? Or for PR/MRs an interface that shows the diffs with syntax highlighting, toggleable unified and side by side diff views, ability to comment within diffs and continue discussions within them (maybe even threaded)?


I don’t mean to be rude, but surely you’ve used an email client that supports threading before?
I think I used elm at one point. (checks) Yeah, it doesn’t support threading. But everything after that that I’ve used for any length of time has.
I’ll check out Thunderbird’s interface again, tried it more than a decade ago with a mailing list and it looked meh. Nothing like lemmy.
