One suggestion: I annotated a pdf with adobe acrobat (on android), and that seems to have gone over well to metapdf, but the default adobe highlights are ugly bright yellow compared to the ones MetaPDF adds. Is it possible for metaPDF to just interpret those default highlights made in Adobe as the default highlights of metaPDF?
One bug: I deleted some highlights and sticky notes that I made in Adobe acrobat (on android) with metaPDF, and replaced them with highlights with comments, which is a nice option in metaPDF, but one I hadn't spotted in Adobe. When I opened the pdf in acrobat (version shown below) on a macbook air. I get the error message "Dictionary keys must be direct name objects." If I click OK, the same error window shows up again.
Adobe Acrobat DC on mac.
I can email the pdf on request.
Second bug. The annotation report on the lefthand side of the paper nicely shows the highlighted text snippet, but has trouble with more exotic characters. The pdf itself shows the characters as intended in metaPDF
"The Chronicle ofS 0e 0eert knows merely that the plague ( wab 0a 0a’ ) spread throughout Persia,India, and Abyssinia (al-Habasha)"
"S 0e 0eert" should be "S ́eert", and "wab 0a 0a'" should be "wab ̄a’" (but with the "-" above the "a").
