Here are a couple of problems with Grammatical Relationship section in L5 BWS.
1. doxa is not the subject of periballo in either of these examples. Solomon is the subject in both Mt 6:29 and Lk 12:27.

2. The headings for "Used Adjectivally" and "Modified by Adjective . . ." sections are really confusing.
It is clear in the first few sections that doxa is the "Subject of . . ." the results of that section and the "Object of . . ." the results of that section.
But the sections "Used Adjectivally" and "Modified by Adjective . . ." seem to be the wrong headings for those sections.

kurios is used adjectivally to modify doxa.
But based on previous sections, one would expect a list where doxa is used adjectivally to modify whatever words are listed.

"kurios" is the noun that is modified by the adjective "doxa".
But based on previous sections, one would expect a list where doxa is modified by the adjectives that are listed in following results.
This has been a problem since 2009, see my original thread on it here: http://community.logos.com/forums/t/6287.aspx.
Seems like it would be a very simple fix to clarify or exchange the headings in these sections.
