Suggest a modification to enable sections and sub-sections to be dragged and dropped within the checklist so it is quick and easy to change the positon or sequence of the sections and sub-sections within the checklist.
This would make it much easier to write, adjust, and amend checklists.
More details:
I have changed the numbering of a section within a checklist, then the sequence changes automatically. Section number can be changed if you click on the section number, then use delete /backspace to create space, then enter the new numbers. This is how I make changes.
One issue though, the numbering of the sub section is not updated automatically, hence has to be done manually.
