an rmmv plugin

nameTheSavesAndExport.js

"use strict";
/*:
 * @plugindesc edit save name ; load from file ; export a save to a file
 * @author agold404
 *
 * @help this plugin adds 3 options in 'Window_Options':
 * 1. edit a save's name: The save file title will be: "game_title - your_custom_name".
 * 2. load from file: This is used when: you need to test multiple platform, but you don't want to play again to reach the save point.
 * 3. export a save: export a save to a file. This acts as a download.
 * 
 * This plugin can be renamed as you want.
