This is based on the same idea that was used in Bug 10902 (pushed to 21.11; https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=10902). I think it might be helpful to have the same kind of highlighting feature in other areas of Koha for consortiums. Specifically, in this case, highlighting the logged-in library when looking at circ history. However, I'm not sure if this would be "too much of a good thing," i.e. if we started adding highlighting all over the place, is it going to be more of a problem than a solution? I'm open to input on this. :)
