PDF renaming script for Thunar custom actions

Hi!

Here is another script that may be useful. I have to collect lots of PDF files at work. Most of them have filenames like "22354345.pdf" after download and it is very hard to search for the right document from the filemanager. So I made this script that helps to rename these pdf files in a meaningful way without typing. The script extract some lines from the content that may be used as a title and offers them for renaming.
It has a number of dependencies, like Yad (Zenity), convert (xnview image convert tool, optional for preview), pdftotext, detox.
Recommend this script for all xfce-using scientists out there.
