I am gonna try to make an application for those
RPG Makers out there.

The general purpose for the application is to organize and plan
your game. This is helpful for:
Game Development

As for the features, here are some I thought of:
*Character Drafting/Planning
*Map Desigining/Planning
*Plot Drafting/Planning

Best part, you don't need graphics, just objects with shapes.

In what you can help:
Give ideas on what could the application could have besides the ones listed above.

Curious, what coding language/program are you using to develop this?

I am learning Microsoft Visual Basic, so that may be the one.

Ah, I see. That seems like a good place to start.
