Lots of trouble with it in latest WP/Gutenberg

Very straightforward plugin to set up, and probably worked great in the older days. But unfortunately it’s too glitchy to use with the latest Gutenberg editor. Custom statuses won’t show up the newly reworked post status pane (WP 6.6+), but do show up lower down in a separate pane. It also messes up the behavior of the Save/Update/Publish button in the editor to the point where I’m totally baffled about what it does anymore. For example, if you make a change to a DRAFT or PENDING post, there’s no longer an UPDATE button. There’s a SAVE button, but it behaves erratically—like automatically publishes things without warning. So I find it unfit for public use at this point.
