Hello. New Godot dev here o/
I find it confusing that Godot is said to have scaleable GUI but all position and size fields are in pixels. Anyway, I'm unable to get what I want, like the system doesn't work intuitively.
Also, immediate problem is the text size. I'm unable to scale the text, or not change the font larger, or open a different font because the font browser has no fonts!
Anyway, I'm here to stay. I'm making 3D 3rd person game for learning purposes now.

It is a little confusing. The pixel positions are relative to the anchor point, which moves/scales as the screen changes size. When you have a control/ui node selected, if you press the “layout” button on the top of the editor window, you can see some preset selections for various anchors.
This page on the documentation has an explanation and shows the “layout” button: https://docs.godotengine.org/en/stable/tutorials/ui/size_and_anchors.html
Also, immediate problem is the text size. I'm unable to scale the text, or not change the font larger, or open a different font because the font browser has no fonts!
You need to make a new dynamic font, then in the new dynamic font find the “data” field and then browse for your font there. Then you should be able to use a font if you have a font in your project. The dynamic font properties also has a size property so you can change the size of the text
