A cool tool to be sure.
However I feel this tool is a crutch for the stupid way browsers handle web pages and shouldn't be necessary in a sane world.
Instead of the bullshit browsers do where they save a page as "blah.html" file + "blah_files" folder they should instead wrap both in folder that can then later be moved/copied as one unit and still benefit from it's subcomponents being easily accessed / picked apart as desired.
