Hey @SlackHQ it's rather difficult to hang up at the end of videoconference, coz the button is jumping up and down - different participants have video on or off, and as they say "bye" the window keeps changing height to show or not show their video :D
Thanks for the feedback on this Josef. We can see how the panel remaining the same size, and in the same position, would help with usability, regardless of people having video on or off. We'll pass this onto the team for you.
