I just was looking at πρεσβύτερος,
in BDAG. When I clicked on the gear icon and then paragraph view,
the article disappeared except for the single entry word πρεσβύτερος.
I have experienced successful use of paragraph view on another word I looked up a day or two ago.
It made the lexicon more readable. (I commend you for that).
I do use back background with green letters as default. This may be another of the black font on black background issues. I haven't checked that yet.
Thanks for your help
