Existing Marvin annotations back to Calibre?

[tozzi]

Hi!

...after IOS8.3 the IOSReaderApp and finally MarvinXD stopped working... OK!

But: Is there a way to bring back already existing annotations from my read books to calibre? Export/import... ?

I'm working a lot with annotations and bookmarks and need to bring them back to calibre. Which ebook-reader will replace marvin for me, until the IOSreader-app will be working again?

Workaround?
HOWTO?

**EDIT***
There is a possibility to EXPORT annotaions and send them through mail...
It's a "mrv"-file. It looks like something html/xml-formatted which has to be brought to a readable format and finally added to the information-column in calibre.
Is there a easy way to convert this mrv to a formatted rtf or something compatible to calibre???

Since the annotation-sync is only oneway, from marvin to calibre, I would really appreciate the highlighted annotations saved into a storeable file/folder...


Thanks a lot for a helpful answer...
