A recent thread reminded me about something I asked about a couple of years ago:
Say you're working on a PB that you intend to share, and the author specifically references the LXX. You don't want to use a simple automatic link, because the vast majority of readers will then see a non-LXX based translation in the popup. And you don't want to link to a specific LXX, because not all readers may have that particular edition. What you want is to link to the reader's highest prioritized LXX -- a level between a reference link and a resource link -- but unfortunately that's not currently possible. You have to use one of the two less than ideal options.
I presume this problem occurs when Logos creates books as well.
I also presume it's a problem that will become more and more acute as more and more Orthodox books and users are added. Hence a problem that should be on your horizon, if it isn't already.
