[Enhancement] Improve the method for managing Indentifiers
I regularly use the identifier links to access the different sites (Goodreads, Barnes & Noble, Amazon, etc.) to read reviews, other books that might be similar to what I have in my library. I think this is a great feature of Calibre.
I find it quite difficult to edit these tags. When I load a new book I make sure there is an identifier to goodreads as I have an account there. I also make sure there is an ISBN number. 90% of the time these identifiers are loaded as part of the metadata download. There are times when the values downloaded don't point to the correct edition. Changing the ISBN number is easy using the button provide. I just have to make sure the ISBN number I want is in the clipboard. Other Identifiers are not as easy. Some books end up with several identifiers and some are quite long. Trying to scroll over to the correct value, select it and replace or even deleted it can be problematic.
If there was an interface like that available for tags, the process of managing identifiers would be much easier.
I currently use Calibre version 2.12 on Windows 7 SP1.
