Syncing Booksmarks with android

[rich.h]

I currently use a Kobo Clara HD for my main reading, and my library management is done exclusively through Calibre.

If possible I would like to also be able to use my phone for the times when I don't have the Kobo with me but a few minutes spare etc.

Is there any way to have the Kobo add bookmarks to epub files that can then be syn'd to dropbox etc to allow an android reader app to pick up where I left off.

I have tried using KOReader, and whilst it functions perfectly it has a horrible shelf interface, since my book files are in folders laid out by Calibre (Author/Series), KOReader just gives me a file browser system which doesn't well for me.

On my phone I would use Calibre companion so I can view the genre tags etc I have already created.

Is there a better app solution out there for this I haven't yet found, or is there some setting in KOReader to give me a proper library bookshelf?
