How do you place multiple features in the feature tree into a folder simultaneously? When I try to drag and drop multiple features into a folder I get the error message "Cannot drag/drop multiple objects in the FeatureManager tree, only the last selected object is dropped." (Figure 1).
Not the full answer, but I figured out the workaround while typing the question. Adding the features you want to move to a folder (Figure 1), moving the folder (Figure 2), then deleting the folder (Figure 3) does the job.
