I would be interested in your advice and assessment of the PR quality, so I can adjust/improve things on my end. Appreciate your responsiveness and consideration !

[sergiomb2]

to help please rebase your main repo on top of sergiomb2:main and than break last commit into multiple commits.

git rebase --autosquash -i HEAD~8
replace pick with edit (e for short)

git reset HEAD~
git rebase --continue

I understand now what you wanted. I'll make sure in the future to do smaller commits, each being a specific functionality.
