Welcome to Defold! Defold is indeed more bare bones than Unity and Godot. This is mostly by design to get a lean and performant engine.
When it comes to the editor and scene editing we are about to release (in Defold 1.10.4 in less than a month) a configurable scene grid:

One of the next steps is to add snapping of scene elements. I can’t say exactly when this will arrive but I expect some improvements to come during Q3.
