Difference between Kamma, Kammanto, and Kammanta?

### Question Hi all, i would like to ask if anyone knows the difference in meaning between these three pali words: * Kamma * Kammanto * Kammanta ### What i've found so far I can see from looking at the pali words for "right action" that this is called "samma kammanto" (sometimes "samma kammanta"), so i'm guessing that these two are the same? I'm also guessing that Kamma is a more general term which includes speech and thought/intention as well as physical action? ### Context I'm building a to-do-list and life-organizing application and since i have a Buddhist background i'd like to give the application a name inspired by Buddhism
