The idea is pretty straight forward. Currently, when you copy a vector (by finding one in the Details panel and right-clicking then selecting “Copy”), there is no easy way to get it into a Blueprint graph. The best thing to do is to manually copy each component of the vector and paste them individually into a “Make Vector” node.
So, my idea is that whenever the vector is copied to the clipboard, the “paste vector” option would appear in the Blueprint graph right-click context menu. Then, when you click the button, a new “Make Vector” node would be created with the parameters filled out.
The idea wouldn’t need to be constrained to just vectors (I just used it as an example). It could be applied to all of the common structures (Rotator, Transform, Linear Color).
