Conflicting BibTex Keys

[jdpetticrew]

Hi,

Sorry if I have missed an easy was to do this.

After appending a .bib file using doi2bib, I run bibcure to tidy up the .bib file. However as part of this tidy it doesn't detect when there are several entries with the same BibTex key. This is a particular problem in my field, which contains some very prolific authors who are capable of publishing multiple 1st author papers a year.

Would this functionality be possible to add this functionality, with the option to append the offending entries with a letter i.e. Author_2017a, Author_2017b etc.?

Another way around it may be to allow for custom bibtex key format? Similar to Author_Word_Year, where word is the first not "A", "The" in the title.
