I got excited about the possability of being able to see the manuscript evidence for a verse or passage so I undertook a project. Add this file to your library as a PB. After it is indexed do a search like this
<bible intersect Matt 1:1>
The search will list the manuscripts from earliest to latest, Papyri first and Uncials second. I am working on the Minuscules now but they will take a considerable amount of time.

I'm sure there is something I have forgotten so let me know if you find errors.
