[INFO] Another file renaming app with a similar design to szyszka

[the-liquid-metal]

There are many file renaming apps that I found, but only one caught my attention: PFrank. You can download it from:
https://www.majorgeeks.com/files/details/pfrank.html or https://www.softpedia.com/get/System/File-Management/Peters-Flexible-Renaming-Kit.shtml. This app is my best friend for years. It saved my life dozens of times. Everything i want can be done. I never found a single problem while using it.

Last version of PFrank was in 2010. Even though it is free forever and works well, i still love to use open source app. After years of searching, no application comes close to PFrank.

All my proposals for improving szyszka are inspired by PFrank. So if there is any issue that is not clear to you, please refer to PFrank.
