Could we se in Logos 10 a special window with two columns for the LEB, where the scripture text is on one side and a tabbed second column on the other?
The tabs would be FSB notes, atlas, and anything else you could want to put in there.
I was reading Acts 19.1-10 today in the RCL Daily about Apollos in Corinth and Paul in the upper country/interior part of the country - - it would help to have a map there without having to click or double click.
Since it would be tied to Logos/Lexham/Faithlife products, you own the rights to all that.
