Show Team name on Label if Channel is "General" in all areas including "My Activity"
This isnt limited to My Acitivities area but its a start, ANYWHERE the channel name label is "General" you really should swap out for the team name. In the screenshot you can see just how useless knowing it was posted to General is. Think about being a member of many teams and posting in general in all of those areas. Think about even if I am posting to just a single team not knowing which team.
Simple change but a functional one. Mobile clients seem to already do this btw. As a Windows Admin I am never happy to see mobile ahead of a desktop app.
