Maintain formatting for new markdown lines

Issue

When typing a markdown list it can be a little annoying to continually type the bullet/checkbox/number each time I add a new line. I'm so used to using other software that maintains the formatting on new lines.

Proposal

Maintain formatting of markdown when new lines are entered.

For example:

• If I add a bullet point and hit enter
• The next line should automatically start with a bullet point

We should do this for bullet lists, numbered lists, and tasks lists.

This is the same behavior in word processing software (Word, Google docs, slides, etc)
