@plk Do you think the request is reasonable? I'd say it is not really a problem to properly enable 'strict' modes of the 'idem' tracker, and it seems easy enough following the example of the ibid tracker.

Hi!
In the manual, it says about idemtracker=strict:
I think ‘idem’ replacements DO get ambiguous as discussed in German on http://www.mrunix.de/forums/archive/index.php/t-72860.html where no one came up with a solution.
Of course, if there are multiple works by the same author in one footnote (and only works by that author!), and another one in the next, idem is no problem at all:
1: Taylor, Zebras; Idem, Tigers. 2: Idem, Zebras.
But consider this case: Let's say we have two books with the same shorttitle from author Taylor and author Potter, let's call the books "Rabbits" and we use a footnote citation style with author, shorttitle.
If I had \footcite{taylor} text \footcite{potter}, the output would be: 1: Taylor, Rabbits. 2: Potter, Rabbits. OK.
But if I had \footcite{potter}{taylor} text \footcite{potter}, the output would be: 1: Potter, Rabbits; Taylor, Rabbits. 2: Idem, Rabbits.
How can the reader tell which book is meant?
Even if the books didn't have the same title, it would still be confusing. Let's say Taylor wrote "Rabbits" and also "Cats" and Potter "Dogs" and imagine there are dozens of citations in an article.
If I now have \footcite{taylor_rabbits}{potter_dogs} text \footcite{taylor_cats}, the output will be: 1: Taylor, Rabbits; Potter, Dogs. 2: Idem, Cats.
Now the reader has to go to the bibliography to find out that "Cats" was written by Taylor! I think that's really confusing, even though in this case, there is at least a way to find out, different from the example above.
That's why I suggest providing a real idemtracker=strict and idemtracker=constrict. I only had the problem with one citation in a small article so far and as there weren't any other occurrences of idem, I just switched to idemtracker=false, but that's not a solution in general, as in other places, I would really like to have idem! If it's not possible to provide a real idemtracker=strict and idemtracker=constrict, I suggest providing \noidem and \noibid commands as there were with BibTeX so that at least I have a chance to resolve such issues manually once I find them.
Thank you for your great work with BibLaTeX!
Take care,
Lorenz
