a repackaging of https://github.com/mtimkovich/slippi-renamer in Electron.
EXTREMELY barebones but functional, no Node or console commands required.
- download and run the .exe from the releases tab
- choose your folder
- all .slp files within the folder and subfolders will be renamed
Ideally I will replace slp_rename.js with my own renamer and allow some options. One day.
