My biggest issue with the current export format are the code blocks. I like to edit using a dark theme, so the code ends up being colored in a way that looks good on a dark background. Upon exporting, however, the code is put on a white background, making words colored with orange, light green, ect. hard to read.
It would be nice to either set it so code boxes have a dark background, or be able to alter the code color scheme when exporting.
Pictures seem to export very poorly to PDF as well, many of my embedded images seem to come out with very poor quality/resolution
