Improved/automated management of uploaded media
File versioning should be automated. If I share "image.png" in a chat, and then share a different "image.png", I don't care what the name of the image is, so long as both distinct images appear in the chat history. At the moment, I get prompted to overwrite or save the "image.png" as "image (1).png", which is disruptive.
Moreover, choosing the "overwrite" option has in the past created situations in which I am looking at one version of an image on my screen and a coworker is looking at a different version of the image on his screen. This situation should never occur--every team member's screen needs to consistently show the same thing.
