I mostly do everything in sequence. Unless I am stuck at that scene, then I would jump to another scene.
So far, I didn't use a proper time line format for my stories.

BUT! Currently, I have this intense multiple fighting scene that I kinda get lost while writing it. So I plan to have a timeline. Just to see which ones happen concurrently. My intention is to be able to have a 'cue' leading to another fighting scene and to another.
