Part of the switch to the new PDF library that I'm using is that I have easy access to the bookmarks in PDFs.  I've really had my hands full with my day job and trying to get the printing/exporting features finished, so I haven't been able to add this yet.  Sorry for the delay.

I look forward to this feature to simply locate the partitions of a pdf file from its bookmarks
I hardly no need to create bookmarks MobileSheets to control complex page turning, my page turner PageFlip makes enough the matter
I was interested in MobileSheets primarily for its quickly page changing and resizing to fulfill optimally  screen size... 
EBookDroid application is full of good features but is not that fast as your's 
but I've been a little disappointed after my purchase when I realized that this feature (navigating with pdf bookmarks) was not present as in any basic pdf reader
I must also say that I am a music teacher (since 1974) and that I have accumulated thousands of compositions, adaptations, teaching materials that I gathered in pdf books I patiently indexed .. . I do not want to start all over 
thank you in advance for adding a navigation feature from original PDF bookmarks
