suggestion to the order list

[Benature]

if I tab in a ordered list, it would go like this

1. a
2. b
    3. c

it would be better if it go like this (tab then the number change to 1)

1. a
2. b
    1. c

Looks similar to #32 but this is real-time renumbering.

moreover, if the first line isn't numbered as 1, it will not change to ordered list (in preview)

1. a
2. b3. c(the first line is not 1.)
 
1. a
2. b
    1. c(the first line is 1. )

so it's a bit troblemsome to change it everytime

Okay, I see
