Known Plugins has a nice list overview but it can’t be exported or copied and pasted.
The list shows the name, format, category, manufacturer and description.
Ideal to be able to export and have a quick overview of your plugins when on-the-go for example.
The Favourite Plug-in Subsets has an ALL Instruments.xml when Open in Finder you can get this file and open it in an editor / browser or spreadsheet,
Low priority feature request I assume to make the Known Plugins list view to be able to export or copy / paste.
Get a copy of DB Browser for SQLite ( https://sqlitebrowser.org/ ) and you can open the patch database itself, which is the file presets.db found in the Unify/Libraries folder. WAY more powerful than a text editor, and includes an "export to csv" feature.
