As an alternate to the Plex (I don't see using both at same time) have a filterable list (think simple spreadsheet or grid) where you can filter and sort columns. Columns would be adjustable but at minimum Thought Name, Type, Tags, Create Date, Update Date, Attachment Exists. You would select on the grid and the note would be visible. The idea is you could mass update Tags and Types, or you could rapidly move through a list of notes.

This is discussed here
