it seems that local PDF file annotations are saved directly to the file, but for the PDF files directly opened from cloud services, e.g. dropbox - their annotations especially drawings are lost forever...

the `<filename>.pdf.an` seems to be a zlib compressed plaintext file with bookmarks; hence as far as i can see it is not in a standard format like `.fdf` all my annotations and notes are lost.
```
zlib-flate -uncompress < filename.pdf.an > OUT_FILE
```

i would expect, at least a warning when annotating cloud cached files (since they are also locally saved in `/Books/.MoonReader/cloud/` folder) that they aren't stored within the PDF file itself. and when closed irrecoverably lost.
