Manages 1000s of pages of technical .pdf file

I have dozens of technical manuals stored in directory on Google Drive which saves me from having to lug very heavy document bags. For a few mission critical manuals I need to keep the off line and organized which this app allows me to do.

I wish it permitted downloading of entire directories, rather than forcing me to recreate the directory structure to organize off line docs. Adding this feature would be a winner, and make me pry open my wallet.
