hi,
I installed Calibre portable on a thumb drive.
I would like to use tags to group my books.
Out of the box there are no tags which is understandable.
How do I setup my list of tags so I can use the dropdown tag box under edit meta data.
Can you nest tags like say
Math
__general
____matrices
____Taylor series
____Bessel function
____DE
any help would be much appreciated.
