One thing that i think is really missing when it comes to the Items, is the ability for the team to have a discussion about the task in the form of leaving comments on it. Similar to Trello.
You probably want a button on every Item, like a chat bubble that symbolizes “Open Discussion” and a new window or sidebar would pop up that opens a simple comment based discussion. Like Trello but simpler. What do you guys think about a separate Item view like that anyways?
