Unable to find a script to list Blogger (blogspot) posts with label

Hello everyone
Two weeks ago I came across a script which lists all of your blogger’s(blogspot) blog posts, with a specific label if you choose.
I’ve lost it and couldn’t find, searching endlessly for the same.

  • It had a repository with script
  • readme file had a link to Demo, it was a web app which asks you to enter url and select couple of options
  • then shows list of posts AND a code specific to the options you selected

Please help me find it. Thanks so much.
