There’s a lot of naysayers, who insist that game engines like Godot shouldn’t be used for drawing application UI as they tend to defender the entire application every frame, rather than just the parts that get dirty. They’re not wrong in that it’s not the most efficient way to do it, but it still works and is fit for purpose in a lot of cases. I put together a Godot based android app in about a week with very little Godot UI experience. That to me is far more important than absolute efficiency.
