Please add a way to copy a message's raw markdown source on all platforms.

For example, on Android, I can copy the message text, but only unformatted, while I've read that the iOS version has the ability to fully copy the markdown already. However, on a PC, I can't actually do either of those (well, I have to highlight the whole message to copy it unformatted), which is a great inconvenience. Please consider adding this feature, thanks in advance.
