you should be using viewports to create your drawings. But when you do you might find that it is slow to go in and out of the viewports to edit the annotations. If you change the edit dialogue box for viewports, you can make it very quick to enter a viewport to edit the annotations. If you right click on a viewport you can choose whether you want to edit the annotations, edit the design layer, edit the crop, or edit the camera. This is also a technique to speed up making changes.
