The oldest feature that has not been released is Instagram Import.
I had a working implementation on April 26th, 1 month before the project name or code was even announced. It's in the git history https://github.com/pixelfed/pixelfed/blob/dev/database/migrations/2018_04_26_003259_create_import_jobs_table.php
This and remote follows are my priorities for the next day or two!
@dansup Any chance of opening up registrations on .social again at some point?
