The collaboration tool is a nice addition in Spotfire 7.5. Currently in the webplayer it is only possible to see if there is a conversation going on by starting a new conversation. By doing so also some little symbols are shown in the visualizations where there is already a conversation going on.
Please create an option to show this indicator without starting a new conversations. Besides please create a button or something so that the ongoing conversations can be seen in the webplayer.
