Been playing around with your editor.

Couple more questions have arisen. When I was editing a component or I think I was adding one, I for some reason replaced an excisting component.

Maybe there could be some sort of undo function?
Being that I accidentally replaced one component with my new component, I figured that the only way to get the original component figures was to reinstall the original mod files. Doing so, of course replaces any changes that one might have made with the original files. So when it comes time for a new Version of a mod, any work you yourself might have done is going to be replaced. Is there any way to counter all of this?
Long winded I know, some day I will learn the art of one sentence descriptions.
