Only tested in AppImage on Linux. Non-file (including folder) will be ignored. This behaves like the UI's file dialog. You can use the shell's expansion syntax to add multiple files. See discussion at https://github.com/whyboris/Simplest-File-Renamer/issues/20

😓 sorry I still didn't get around to this PR -- still trying to finish house stuff. Hoping I'll find time for some coding in 2025 🤞
