I've begun working on an extension. So far: you can now define the number of battle members to display and you can now show the display name of a map instead of the editor name.
https://raw.githubusercontent.com/DreamXRMMV/Rpg-Maker-MV/master/DreamX_Ext_SaveCore.js
* @param Map Display Name
* @desc Show make display name instead of editor name. default: false
* @default false
*
* @param Battle Member Display Count
* @desc Number of battle members to display. default: 4
* @default 4

@Yanfly's SaveCore plugin is a step in the right direction for a customized save menu, but I feel it could have a lot more options to make the screen that much more appealing.
- Showing the map's 'displayName' instead of it's actual name
- Option to show additional info from the actors, before the columns start below
Class, state icons?, HP/MP, JP?
[*]Gauges?, Experience?
[*]Option to show the value of a variable without it's name
[*]Text AND variable (label your own variable)
[*]Change the number of columns
A lot of this can be done through use of in-game variables, but without being to easily change the number of columns on screen, you can't make things line up with the actors up top, and for certain things, you'd need to plug in to a function that refreshes a lot to make sure that the info is up to date when it's put in the save file.
I'm not sure if there are any plans to expand on this, but those are some of my suggestions.
Thanks,

It always helps to make a mock-up example of what you want.
