Better sending of files between team and personal OneDrives.
It would be awesome to be able to send files from my personal OneDrive (in the Files section) to one of the team drives.
When you right click it could say "Send to team...". If you click on it, it will pop out a list of your teams. You select a team, and it pops up with a dialogue similar to the Share File dialogue in chat to choose where to save it.
Additionally, in the Team > Channel > Files tab, there could be a Add File from My OneDrive, that pops up with a Dialogue similar to the Share File dialogue in chat.
