Great start! Would you mind:

• add state support also to the other imperative apis .replace, pushTo, replaceTo ?
• add state support to Link via props <Link href="..." state={...} />
• ensure that it is available and returned in the hooks (eg in useRouter) by adding 1/2 tests there too

Thanks!!

@albertogasparin Added state to replace, pushTo and replaceTo. I also added state to the Link and changed it so we are not copying state and just using it from location. Due to the state being in location, I am not sure the extra setup and changes to the useRouter are needed as the four other functions get tested for a return in state and location is in useRouter

Looks great! I have one last ask: can you mention it in the docs? So it's clear that those APIs and Link accept state and you can find the value inside location

@albertogasparin Added an example and updated Link props, let me know if you need more
