Every animator needs to separate X and Y dimensions on a layer's position values in order to animate fluidly. Yet After Effects make this process unintuitive - you have to right-click and select 'Separate Dimensions' in the dropdown box for only one layer at a time, and if you have keyframes already on that layer separating the dimensions will change how those keyframes animate, setting them to default.

Keep 'Em Separated fixes this for good. Now just click the button and your layer's position dimensions will be separated just like that. Keep 'Em Separated even works on multiple layers at once, works on 2D and 3D layers, and Keep 'Em Separated won't change keyframes that are already on the layer - everything will animate just as it was before you separated dimensions. It's that simple, it's that easy. It's Keep 'Em Separated!
