did a maniac hack on the old lem.el recently, mainly for the 0.19 release. overhauled the logic of all the sorting/listing commands. they should be more rigorous and flexible to update now. various other fixes too. pushed to main, so will hit MELPA soon.
also added unified inbox for replies, mentions, and private messages, and various other minor display improvements.
i also fixed authentication for the 0.19 release, but when your instance actually upgrades (lemmy.ml already has, for testing), it will require you to delete the lem.plstore file in .emacs.d/ and log in again with your password.
& by all means holler if you run into authentication issues during the transition.
