Basically the LiteTween (by Lunnaray) movement behavior. Something like that to make built-in easing and movements smoother. Other game engines like UE4 have this built in, I think C3 should as well.
This is a good idea and we'll probably make an official behavior later down the line. However we'd like to focus on completing the Construct 3 runtime first. In the mean time we will work on the SDK and help third-party developers port their addons to C3.
