Lots of work
Exactly, the hashes can never come back and even if it could be worked around by some method, I'm doing this just to help out, its already taken a few days of work and besides the append function, I don't believe it can/will go much further. Version 2 was designed to replace the functionality of the Create Collection->Add Books from a large list of titles. 2.2 will have this append function back shortly, based on selecting a specific collection and adding it to the end of the file.

As for where it searches for files, the defaults are as is, I am letting the user decide where he wants to go to locate the file, its not technical task to use a browse dialog. There really isn't an alternative as everyone's path to json/books is different.

Its a shame that amazon didn't feel the need to release a similar tool with the firmware upgrade and I know it sucks that those using macOS/linux are currently left out (that may change if I get more free time, having some life issues atm).
