Thank you, @jnashhawkins. I’m going to read it right now.
The Tiny MCE Advanced is a nice suggestion, altho my problem mainly happens on navbar tho. Got to think about it.
EDIT: I red the article you suggested and got super confident on using anchors. I mean, even the cons weren’t that bad, since I’m aiming for user experience above page time. Altho it won’t solve my problem (as I listed above, which remains on navbar), it is indeed a very good read.
I’m guessing I will try something like using only custom links. Somehow, I think wordpress won’t let me mix them (parent with dynamic page link and those static custom ones). Going to test it in this afternoon.
