Looks good in general!

I wonder why we are using DispatchResultWithPostInfo as the return type though there is no post info?

Thanks!

For the DispatchResultWithPostInfo you're right that it's not needed. I just copied it from the previous pallet for the first extrinsic I added, then reused it afterwards 😁. Fixed it now.

All functionality intended for this PR has been implemented, and it's ready for final review 🙏

@shaunxw thanks for the approval!

I was thinking, instead of merging it directly, to keep this in a 'live' branch. All consecutive PRs would be merged to this branch instead (or I could create another branch to aggregate all PRs).

This would keep the review of PRs light(er), while also providing one big overview in the end, before everything is merged. What do you think?

Love this idea. It definitely helps with the review process.
