I’ll note that a number of groups and forums send mailing list like emails (google groups, django dev being a big one) and that notifications can be threaded from places like Github with the right client.

Thunderbird has good threading.

Roundcube webmail is also capable here. Though when I have had it working it didn’t include sent messages… which is not great in my mind.

Thunderbird has good features for mailing lists and threads.

Yeah I’m thinking about fuse filesystems and hotplugged USB keys though. There was a time when the feedback about devices being ready to unplug was bad for users.

This answer suffered the fog of time. Never needed it with the unmount command.

Uhm, been a while since I had to think of this but pretty sure you used to need to do that the other way around. Sync before unmount, else things may still be being written to disk.

Designers need to wake up and realize their job is to understand what the user wants not what they saw in a wet dream.

“Cohesive”

This is also represented pretty well in Pantheon.

Religions have been doing this for millenia.
