[feature request] Filter in/out favorites in 'Manga Info'

[acg5159]

Is your feature request related to a problem? Please describe.

I would like to be able to filter out manga titles of Manga I have already added to my favorites.
As a optional additional request. Be able to the filter Favorite list by items like Genre, etc.

Describe the solution you'd like
Add A checkbox or equivalent to the 'Filter' Tab under Manga Info to filter out Manga already tracked in the Favorites list.
It seems like the data should be available as the 'Add to Favorites' button is greyed out on items already in Favorites list.

Describe alternatives you've considered
A more complicated solution might be to be able to add a drop down box to offer an additional option:
[0] Include Favorites <- Current behavior
[1] Exclude Favorites <- Similar to check box
[2] Only Favorites <- Inverse of [1]
*Being able to sort and search through favorites list by more then just title would be nice.
