Chat / Conversations while Presenting
I really think it would be beneficial for the desktop app to be aware when someone is presenting and to not automatically pop-up the conversations or chat they are receiving. A lot of times those conversations are meant to be private and having them pop-up in a room full of people is not always ideal. Basically same as Skype having options to not display message pop-ups while presenting.
I personally think there should be a "presentation button" - for some they may want calls / chats to come through even when presenting and in other times, they may not.
I also want an icon that tells me someone is presenting so I know not to chat them. This is SUPER frustrating and very unprofessional when I see someone getting chats in the middle of a presentation.
