In 'Extract Images' you provide a folder and instead of putting the images in that folder it creates a subfolder using the PDF name and places them in there.
That is fine but the user doesn't anticipate it so can I recommend that where the save button is there is a (default on) tickbox saying "Place in subfolder named after PDF" or "Place in subfolder named '(cite name here)'" as this both explains what to expect and also gives user control.
