Sort/Unsorted Option

Great Job with these extension.!!!!

I do not see/know how to sort/unsort the structure view. It kinda needs to be sorted so we can do a human visual search fast. I read there is a -u from the command line for unsorting but not very clear how to do this or the opposite. Could you explain. Regards

Start by checking the existing user documentation and the command-line `-u` behavior mentioned in the issue. Document how to sort and unsort the structure view, including the opposite of `-u`; the work is done when users can follow clear steps for both modes.
