Amazing work! Thank you for contribution! <3

There are some small thing to adjust, I left todos. I can start fixing it in 10h

Note to myself: do NOT forget to update demo.ts and release it :)

Unfortunately there is a couple of todos we should address. If you really need this feature released soon, I can marge and release it in this form. Otherwise I prefer to rethink the implementation to handle edge-cases like [1,2,3][1] and [1][5]

Don't worry, let me check how to address them. I think I will work on them this week end.
