There is an Atom package called Markdown-Writer. Among many other features, it includes a function called
markdown-writer:correct-order-list-numbers. If you put your cursor within a list like this:
1. Ant 1. Bat 2. Cat 3. Dog
And press the shortcut associated with the function, it will correct the numbers:
1. Ant 2. Bat 3. Cat 4. Dog
Is there already a Sublime package which offers this feature? If not, how complex would this be to implement one? FWIW, I’m on ST4.
