Thanks for this utility!
I known I should try to write something using your pdf library.....
but meanwhile... thinking at version 2.0 ... can you add a "sort by path/filename" function in the file grid?
Other useful options could be...
a) more columns (property) to sort on, like date, size, PDF version.
b) load file from a directory, not only with drag&drop
c) back from old times.... be able to run it from command line (this can solve every kind of sorting needs :-) )
