How not to design a video conferencing product?

"Can you please stop sharing your screen so that I can share mine?" "I can't see that part of your shared screen because those buttons are overlaid on top." "How can I share my second webcam without stopping the first?" "Can you please say that again? I missed the last part." "It shows only up to nine videos even though I have a very big screen."

Do you ever feel frustrated due to some artificial restriction imposed by the video conferencing product you use? In this informal article, which some will find quite opinionated, I list some annoying product "features" when it comes to video conferencing.
