Gentleman,

There's such option in the Adobe Reader/Acrobat preferences tab which
enables a change in comment screen font but only in edit mode. I don't
see any info in the PDF reference about changing pop-up font. Below a
comment example in postscript where I searching for such font option:

%%% PRINT A COMMENT
gsave
	[/Rect [x1 y1 x2 y2]

	/Title (Your title)
	/Subtype /Popup
	/AP /R
	/F 64	% 7-bit makes read-only
	/F 128	% 8-bit sets it locked
	/Contents (Some text here)
	/ANN pdfmark
grestore

Any advice about text formatting in comments are appreciated. I
couldn't get proper tabulation - if I want the text be in columns.

Regards --Jack,
