Dot navigation suggestion

Hello, I am texting regarding a suggestion that I think would be very helpful: "dot navigation".

Since it's not possible to write javascript directly on the tool, what about providing this navigation option?

Typically it works with anchors, so the way I see it it would require some kind of side navigation bar/header with dots/icons instead of text (text can also be part of it as hovering/tooltip effect).
That way its position would be fixed and possible to be seen in throughout the pages.
