ok guys, i got a good idea
in ereader, you can sort by title, author and date, the title/author are useful but sort by date is a total waste imho
now here is the great idea, ereader us file's last modified date as the date to sort, use java (or other util's out there), you can set your lrf files' last modified date to be anything, encode to your liking, the ereader will sort based on year, month, day, so essentially it gives you a 3 level hierachy sort!
so you can have 3 categories, encode year, month (only 12), day (31) to your preference, then sort by date.... files will be ordered as you wish
i tried it and it works great!!!
the only catch is, if you set the date older than today, the ereader will modifiy it to be today and void your effort, but i tried a NEWER date than today, for example year 2016, ereader will keep that date, haha
but don't get carried away, i tried year 2088 nothing showed up, what's the max i don't know, but i know 2008-2016 works
enjoy
