Feature request: Allow cost to always be shown for current session

[cmlaverdiere]

Often I'll want to check the cost of a session while the agent is working, so I'll either have to wait until it's done a series of steps, or cancel the current step just to check. This is one of the most frequent interruptions to my flow. It would be a big QoL improvement to have the option to just always show the cost of the current session.
