Auganizer has been dead since Monterey, so I wanted to fill in the blanks left when going back to Logic's own Plugin Manager. The main one, at least for me, was not being able to tell which plugins are currently uncategorised.
Place this macro in your Global Macros group. It will run every time Logic Pro launches, and if any plugins are uncategorised, you will be prompted with three options:
Maybe later: Ignore them for now.
Ignore forever: These plugins will not be flagged in future.
Oh, go on then...: The Plugin Manager will open alongside a list of uncategorised plugins. You can refer to this list as you go through and categorise each one.
