Hi Faterson, sorry for taking long to get back. I'm struggling with one last feature before the next update. It's taking a lot of time to fine-tune (now almost all is OK).
The easy one: Losing the line breaks in exported notes is an oversight. I'll get that fixed in the next update.
The hard one: Exporting highlights and selections with formatting intact is a bit harder. I'll work on it but I might not be able to fit it into the very next update.
