Hi again @gante remade all the changes in this fresh PR..so sorry that you need to review once again. In turn I realized I need to learn more git 😅

[gante]

This time all good 🔥 Thank you for the contribution!

As for git skills -- yeah, they are super important for these large projects. As you've seen in your other PR, one wrong command can create a lot of work. Practice makes it perfect 💪
