Automatic numbering and bulleting of lists

[HItzz07]

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!

I'm definitely open to this, a PR would be welcome.
