How about a standalone Tagging App from Plex?

I am tired of tagging with multitudes of applications for music and audiobooks.
I wish the developers of plex would develop an application that solves a lot of woes. I envisage the following:

Let’s call it : UNIVERSAL PLEX MEDIA TAGGER/MANAGER

Functions : Scraping, Tagging, Renaming and maybe scripting functions for Movies, Serials, Music in General, Classical Music and Audiobooks.
Levels Of Complexity or Pre-sets : Simple, Advanced, etc. based on how much information and details the user wants to retrieve.
Type of Organization for Media files : General, Plex Friendly, Custom etc.

EXTRA FUNCTIONS (if possible): PMS API calls to check and compare with existing media in the library. This would be useful to avoid duplicates.

Maybe in the future, developers can set and finalize a standard on how and what kind pf tags needs to be in and the whole world should follow one standard.

If the above has any value, kindly let me know in the comments!!!
Thanks
