I know that my original directory structure in calibre isn't preserved. But this is very inconvenient. There might be the case that sorting books according to author is good and will take some time to get used to. But still there should be a choice for a user to decide himself. You need to understand me here, calibre kicks ass but what if i decide to switch to some other software in the future , then i wont like the calibre's directory structure to drive to my ebook.
Suppose i have some matlab books, i would rather like them in a matlab folder not sorted according to author. How can sent this message to developer?
