@speakingtohe: plugboards now work with the Sony database, as well as with the books on a Sony. To modify the sony's db, use the special format 'device_db'.
This works very nicely. For example, I use a plugboard to put 8 characters of the series plus the series index at the end of the title. This extra info helps when browsing by author or by title, or by non-series collections.
The plugboard is:
Code:
device_db:PRS505 = ([{title}{series:<.8s| [|}{series_index:| [|]]}] -> title)
