How to list strips in Blender VSE? Suppose the duration of the listed strips changed during the project.
You will need to refresh and rearrange the strips.


In Blender, this seems to be a manual task.  


But After Effects has the ability to automatically align strips.
(I've attached an example of AE to help you understand what I want.)

I want to know if Blender VSE has the same functionality as After Effects's keyframe assistant-sequnce layers.
Select all of your strips you want to put in order and run this script:

import bpy

strips = bpy.context.selected_editable_sequences
strips = sorted(strips, key=lambda strip: strip.frame_final_start)

cleanup = []
for i in range(1, len(strips)):
    st0 = strips[i-1]
    st1 = strips[i]
    cleanup.append( [ st1, st1.channel ])
    st1.frame_start = st0.frame_start + st0.frame_final_duration
for x in cleanup:
    x[0].channel = 1
strips[0].channel = 1



It's a version of this script: VSE script for to add constant gaps between strips?
