A long standing issue I’ve had is inserting a Part, forgetting it’s unanchored, and finding out long after once testing the game. This results in a lot of backtracking to anchor everything, which can lead to mistakes of missing a part, or anchoring something I actually intended to be unanchored.
In the past, this has also resulted in large, unanchored Parts existing inside other Parts, and tanking a game’s FPS from the constant physics updates. My first thought when the game’s FPS dips is that something is up with the game’s code, rather than what should be a static map.
Given that build mode is dead and we’re no longer able to simulate physics until the game is explicitly played by the developer, it makes more sense for Studio to default to anchoring parts when inserting them. The
Instance.new("Part") defaults could stay the same, but specifically when opening up the Insert Object menu and inserting a Part, having it anchored would be helpful.
