PDF comments: see/keep local formatting
I’m missing two things. First, the PDF Comments panel menu doesn’t display local formatting (italic, bold, bold italic) whereas these are visible in Acrobat. Second and most important, when accepting a comment, any local formatting doesn’t translate into InDesign. As if the whole content is treated as plain text.

For a workaround please see my free Acrobat script and blog post here:
Sorry for blogging only in German. But when you download the script and open it with a text editor, you can read installation and usage instructions in German and English.
