1. Add, resize, or remove placeholders from the Master or individual slide layouts to modify the existing design and revamp the presentation. 
   
   
2. Choose a layout for a new slide, change the existing layout, or even create your own layout to facilitate reuse. The edits made to the layout in Master view will reflect on the slides following it. 
    
3. Make uniform changes without editing each slide separately using the Master slide in the Master View. This helps you apply changes to all the slides in one go, thus saving your time and bringing consistency to the presentation.
   
   
4. Add header and footer placeholders in the Master slide or in individual slide layouts to include slide number, footer message, and date. You can position the placeholders anywhere within the slide. 
   
   
5. Rearrange, resize, align, or rotate placeholders in the Master or individual layouts using the Arrange panel. This helps you to re-order the distorted objects in slides. When you adjust objects in the Master View, all the slides that follow the layout will have the text, pictures, images, or shapes rearranged, moved, and resized.
   
   
6. Add a background to the Master or individual layouts to reflect the style on slides in the presentation. For example, add a picture that suits your subject as the background in the Master. The fill will uniformly apply throughout the slide decks. 
   
   
7. Uniformly apply text format properties such as font, color, size, and style to objects in every slide using the Master. You can also customize objects on individual slide layouts. The effects will appear on the decks following that layout
   
   
8. Additionally, you can customize, duplicate, rename, delete, and organize layouts in the Master View.
