11. If I download an image from the internet and post it into a chat, there will frequently be a popup that says "A file named ui.jpg already exists.". Why would I care what the name on the backend server is? Just rename it and let me send it. 12. Users over 40 in my Teams instance seem to have a hard time distinguishing between the UI for starting a new thread and replying to an existing thread. 13. It's system for highlighting messages you haven't seen is pretty janky. It frequently highlights my own relpies as messages I haven't seen. 14. If someone posts a message to any thread in the current channel when I am typing a message, the message editing box will lose keyboard focus. 15. It uses its own notification system instead of the system one. I basically have to have the left half of the window always visible so I can manually check for visual indicators in the app itself. 16. Sometimes you can pause gif playback, sometimes you can't.
