Hi All,

Based on the discussion here and in the FolderIn/FolderOut thread, I have just committed to master support for two new plugin features available in edit, output, and validation plugins:

bk.get_epub_is_modified()
   returns boolean True if the epub inside Sigil has been modified 
   but not yet saved to disk

bk.get_epub_filepath()
   returns a string of the filepath for the epub currently open in Sigil 
   or the null string "" if the current epub is unsaved/untitled

Here is snippet of code you can add to your current plugin.py to test these features available in any build of Sigil from current master

   # status of epub inside Sigil and its current path
    if bk.launcher_version() >= 20180122:
        print("\nExercising: get_epub_is_modified and get_epub_filepath")
        print("epub inside Sigil is Modified: ", bk.get_epub_is_modified())
        print("filepath of epub open inside Sigil: ", bk.get_epub_filepath())

These new features will appear in the next release of Sigil.
