Tools frame
     
    The tools frame contains the controls associated with the possible 
      actions on the document. These controls are grouped in "tabs" dedicated 
      to each phase of the processing.
      
        - The  "List" tab is used to build the 
	  list of images or movies to process,
        
- The  "Align" tab is used to align all
	  the images,
        
- The  "Analyze" tab is used to 
	  analyze the quality (or sharpness) of all the images,
	
- The  "Stack" tab is used to stack 
	  all the selected images into one,
	
- The  "Process" tab is used to 
	  enhance the stacked image.
      
To select a tab, just click on it.
      It is impossible to select another tab while alignment, analyze or 
      stack is running.
