As of now, there is no provision to move features scattered in a feature tree at once. But there is a workaround for it. This is not something you might use daily but if you have long feature and time comes for house-keeping, I think this should come as a handy tip.
Follow the simple steps below:
Press "Ctrl" and multi-select all the features that you want to move.
Once selected, right click anywhere inside the feature tree and click on "Add to New Folder".
Notice that a folder will be created which will contain all features that you had selected. Currently, folder is created below feature "Revolve7"
Now you can easily move them up and down (provided you are trying not to move above its parent feature). If you had tried to move them without creating folder then SW would thrown an error that "Non Contiguous features cannot be added to a folder" (which is exactly what we are doing the other way I guess 😛 ). Now the folder is moved below "Revolve5"
Once you are satisfied with the location, you can delete the folder and all features will be placed in the order that they were created but one after another unlike scattered.
