Using localForage-cordovaSQLiteDriver w/ YEP_SaveCore.js and rpg_managers.js

I successfully deployed localForage-cordovaSQLiteDriver to my RMMV ionic/cordova project.

My SQLIte Database is now accessible and writable through the localForage-cordovaSQLiteDriver interface.

I wrote a simple javascript file to test writing data to it and reading data from it, so that's how I know.

My question is twofold:

(1) Am I correct in my understanding that the rpg_managers.js file is the file that deals with all localstorage.setItem(key, value) commands? - I assume this is Yes, but I just want to double check.

(2) The second and more important question is for anyone with understanding to some of the 3rd party save plugins like Yanfly Save Core work. In Yanfly save core (YEP_SaveCore.js), I don't see him explicitly calling localstorage.setItem and from what I see, he is using he datamanager class. Does this mean his save core plugin is ultimately using the localstorage.setitem and localstorage.getitem commands that are in rpg_managers.js?

The reason I ask is because I need to identify the base area that actually commits the save data, and I need to change that to use the localForage-cordovaSQLiteDriver I deployed. I am hoping the YEP_SaveCore.js is indeed using the rpg_managers.js localstorage,setitem and get item as shown below because that means i can ultimately modify this ever so slightly to use the localforage driver I have configured and I can then save to sqlite very easily instead of saving to the default localstorage.

StorageManager.backup = function(savefileId) {
    if (this.exists(savefileId)) {
        if (this.isLocalMode()) {
            var data = this.loadFromLocalFile(savefileId);
            var compressed = LZString.compressToBase64(data);
            var fs = require('fs');
            var dirPath = this.localFileDirectoryPath();
            var filePath = this.localFilePath(savefileId) + ".bak";
            if (!fs.existsSync(dirPath)) {
            fs.writeFileSync(filePath, compressed);
        } else {
            var data = this.loadFromWebStorage(savefileId);
            var compressed = LZString.compressToBase64(data);
            var key = this.webStorageKey(savefileId) + "bak";
            localStorage.setItem(key, compressed);

Anyone who can add anything of value about how YEP_SaveCore.js might work or use what's in rpg_managers.js would be greatly appreciated.

I died aged 27 to cancer. Then I was reborn in a South-American state. I retained all memories and skill and had a goal from my previous life I needed to finish, but now I was just a 1-year-old girl capable of only smiling at others.

Dreams like this one make me glad I'm able to wake up from them at will.
Found a critical bug the other day with the time system that would have caused none of the NPCs to spawn. Since I use dev mode to test time-based stuff, I didn't catch this for way too long!
