Automatic numbering and bulleting of lists

When we are having notes points wise , like
1. Abc
2. Xyz  

It does not actually add the 2 , 3 bullets upon pressing Enter , we need to do it ourselves.
Same if the case if we use some other bullets.
i.e.
- abc
- xyz
So that can be a good feature to have.

(You can try out bullet things on this github markdown only to get a better understanding of what i said)
Thankyou!
