Okay, so i have an interesting bug with Calibre.
I am trying to export my library to disc, and noticed that despite me having set the save to disc to use title, it uses title_sort instead.
Also, on a slightly different note there is another thing i noticed that may or may not be intentional behavior.
I have a Metadata plugboard that updates the epub title and epub title_sort to add the series and series index to the beginning of the title and title sort when i save it to disc. Doing that updates the metadata .opf file within the epub archive, but it doesn't affect the actual name of the file. So even though the metadata says the title and title sort is:
<meta name="calibre:title_sort" content="The Dresden Files 13 - Ghost Story"/>
<dc:title>The Dresden Files 13 - Ghost Story</dc:title>
the title part of the file name as exported is still just "Ghost Story". Again, that may be intentional, I don't know, but it's not how i would expect it to behave.
I'm using Calibre 0.9.5. I tried to report this to the Calibre bug site but the tracker wouldn't let me register for some reason. This isn't exactly an urgent bug, but if possible i would like to see it fixed. Thanks.
