Open chat tab with shift+ctrl+I -- add a Twitter account. On the right side is a panel with heading "participants". This appears to list those who have sent Tweets showin in the center panel. But what is this "participants" panel for? The following questions are not answered anywhere: 1. Why cannot right click or double click on any of the participants to have some options? Only available purpose seems to be hovering the mouse over a username in the "participants" list pops up a tool tip with information about the user. But nothing can be opened or copied or actioned. 2. Why some of the participants are in bold font, and/or color, and others just in black? What is the meanings of the colors, is it random? Why and for what? 3. Just under the title above the "participants" under (your username timeline) there is a box that can be edited. What is this for? One would think it is for choosing a topic and then being able to select participants to start a conversation, indeed multiple participants can be selected by holding the ctrl or shift key, but for what purpose? Nothing happens, and no right-click options. Can any help be added, can anyone explain? Thank you :-)
