I am in completely favour of spatial solutions, but sooner or later you hit the problem that the graph of associations don't map well to 2D unless you denormalize it (like in databases). Which just means if you want to reference an item in multiple places you have to duplicate them and you loose the link between them. The solution for Muse would be to not put the item in the drawer but the whole area around it as well. Then when you paste it back somewhere you create a wormhole in the space that shows the original place now in a different context. This way you can keep the intuitive zooming and panning and see duplicated areas that update properly. To be fair there are already some ways they try to solve this with their point style wormholes or the "expand and edit content on the drawer" interaction, but I think they should fully embrace that thought space is not linear.
