[AD] Export Persona Enhancements

[fernandolins86]

This is a list of enhancements I would like to suggest for the Export persona in Designer:

• The selection border around selected slices should be visible at very small zoom levels. Currently it's very hard to tell which slice is selected on zoom levels below 50%.
  
• There needs to be a way to completely hide (toggle show/hide) the slices markings (the slice title and its border)
  
• Double-clicking a slice in the Slices panel listing would zoom into that slice. In the Layers panel (back in Draw Persona) if you double-click a layer AD will zoom it in to fit the viewport. This would be very, very useful in export persona too, in the Slices panel.
  
• The Slice Selection Tool selects objects within the artboard instead of the slice. It is far easier to select an object than to select a slice. Maybe the tool should select slices on click and objects on shift+click or something like that? Its name is misleading.
  
• There needs to be actions (buttons or keyboard shortcuts) to select all/select no slices or to check/uncheck the selected slices and invert the selection.
  
  • In fact, it is confusing that selected slices are not exported, only checked ones are exported. Why not make exporting selection-based? Only selected slices would be exported, no need for checkboxes and confusing selection behavior.
    
  
  
• Selecting a slice highlights it on the Slices panel listing but does not scroll to it, this would be quite helpful
  

Thanks!
