When hovering over an R Output that’s being calculated, a small box appears stating that it has been started, and what day and time.

With VERY long-running outputs (talking more than an hour), it’s often unclear if things are STILL running, if they’ve crashed and we just don’t know, and how much longer it’s going to take.

Please include a status bar that updated regularly with information to reassure the user that the output is still running.

Please also consider including an estimate of when it may be finished (I understand this last one may be tricky….).
