How Can I Change Reply types?

Right now, all of content on the platform is shown in an a structured reply format:

-OP

-- Reply A (1st)

-- Reply B (2nd)

---- Reply C (to Reply B) (4th)

---- Reply D (to Reply B) (5th)

---- Reply E (to Reply C) (6th) <--- Here is where it kind of breaks down

-- Reply F (to OP) (3rd)

Something along those lines.

Is there a way to switch to this kind of format?

- OP

- Reply A (1st)

- Reply B (2nd)

- Reply F (to OP) (3rd)

- Reply C (Quote to Reply B) (4th)

- Reply D (Quote to Reply B) (5th)

- Reply E (Quote to Reply C) (6th)

Also making the thread paged instead of continuous scroll would be great.
