make a participants input blocked icon similar to the participant annotating icon

when viewing the participants section and a host is using the annotation tools, you can see that hosts Icon change to a pencil from the default headset & mouse . The same should apply for a Host who has suspended his or her input or transferring a file. Maybe something like the default mouse icon with an X over it? And for file transfer two arrows pointing away from each other while stacked on top of each other?
