Many times you may want to insert some space between objects in the flowchart or wireframes. A really useful feature is to be able to add or remove space within the diagram by using control+drag for adding space, and control+Alt+drag for removing space. This is the exact method that LabVIEW a graphical programming language uses for efficient coding. For example, you are doing a flow chart for for iOS app development UX. If you decide that there should be an addition set of UI elements at a point in your UX that you didn’t previously account for, you can simply use the control+drag to add some space and start adding new elements. Alternatively, if you delete several elements and now your diagram has a gap in it, you can remove the space to keep your diagram neat and efficient to review.
+1! I use this function frequently in OneNote.
