Add hierarchical tags view

[alllexx88]

Not sure how hard it is to implement this. Library I'm working on has a pretty detailed hierarchical books classification, and I've generated 268 respective hierarchical tags if this kind:

I'm not 100% sure, but looks like hierarchical tags view isn't implemented, right? It would be a great asset to have it then. Thanks!

Not easy and above all, not part of the calibre structure as you guessed it

but i guess i can make something about it 👍

[alllexx88]

It's actually part of calibre 😃 And no need to change the db scheme. See here: http://blog.calibre-ebook.com/2011/10/calibres-tag-browser.html
You can enable hierarchical view of tags in form 'Tag.subtag.subsubtag' in calibre. I meant to say that such a representation isn't implemented in silex.cops. And please take your time: it's a handy asset (with so many tags in the lib), but it can wait for as long as needed

wow, never seen this 😸

[alllexx88]

it's well hidden, but I intentionally searched for something like this :D

[mduplouy]

I need to think about this, but I like the feature 😄

i'm gonna push this also on the mysql branch :)
