I had a need to export all of my notes and import them again, and I used the CSV file format for this.
Sadly this throws away all the creation date and modification date info :-(.
Pity. Before, all my notes had a complete history of when I created them and changed them, and had useful information for me using this (basically the ones I had modified most recently were the ones I needed to refer to most). Now this info is all lost.
It would be so easy to export this and allow this to be imported again.
Sure, if people don't want it, they don't need to import it, but if they do, then at least they can.
Basically an export/import should be able to be a lossless operation. Maybe there are other fields which get lost too, but these are the one's that mattered to me.
