Imagine a chat application with Teams that is actually /usable/. I really miss the days of Pidgin.
Fun fact: the KDE / Linux client for MSN had a feature whereby it would notify me (by opening a window) if someone had clicked on my profile in MSN Messenger and started typing a message, but not yet sent it. It was a really nice way of freaking regular MSN Messenger users out.
I cannot remember what the name of the application was but it was very handy.
