New update is in da house !
Changes:
-load subfolders option - by default is False, but state is saving after close
-buttonbar on grid is dissapearing now when you start scroll, touch it to appear
-now MPGQ is making thumb when there is no thumb from tracker (will slow down loading)
-back button added next to rotating buttons
-next and prev image is done by draging not zoomed image up and down

I noticed errors when I try to load all images from /home/user/MyDocs/ it's because of md5 lib from python, it can't generate md5 sum for some complicated filenames :/ I will try to find solution.
