[MrWriterReader]

I would like to style the annotations that I have stored in Calibre. I know how to get them off the reader (Kobo Libra H20), and have deduced how to alter the timestamp, but I can't work out if there is a way that I can globally alter the way that it styles them. I currently have chapter headings and timestamp on a white (more like grey) bar, with the annotation below in plain text. I would like to know if there is a way to style the bar so it is a different colour (or cycles through colours, as Calibre seems to suggest [although I cannot now recall where]), or how to have a page number instead of a (sometimes long) chapter title each time. etc. blah. If anyone can help, I'd be chuffed.
