Calibre Server: 2 Feature Requests/Ideas... "tag cloud"+"word cloud"

It would be something awesome if Calibre's web server had the ability to let people "drill down" by selecting tags or words in book

Feature Request/Idea #1 of 2 --> "tag cloud"

Like:
tier 1> Click on Tag "Earth"
tier 2> Click on Tag "North America"
tier 3> Click on Tag "California"
tier 4> Click on Tag "SanFrancisco"
... to see all library books with the tags: Earth, North America, California, SanFrancisco


Feature Request/Idea #2 of 2 --> "word cloud"
The *MUCH* bigger version of Feature Request/Idea #1

Totally identical

Except it would be a cloud representation of the "X" most used words in the library of books

same 'drill down" ability by selecting words you would piece together... to discover book content you never realized you had



FWIW: Tags are good, but they are not enough.

The closest I can come to approximating this is using the plugin "ENF" and generating a word list of each book and display in the comments.


I would even offer to "buy several pints" of beer for the developer who implements either idea... hopefully idea #2

Is the DB engine robust enough? Would something beefier be neeed?
