I'm not sure if there is currently such a feature as I see it being shown here but I definitely see no such bubble so my request would be to have a number of pending posts shown as a number or at least some color change because currently the only way is to check the link every few minutes.

I'm not sure if there is currently such a feature and for some reason doesn't work for me but would it be possible to add a functionality that shows some kind of alert when there are pending reviews (first posts/late posts)?

Currently the only way I can check if there are pending reviews is by checking the link every few minutes which is inconvenient.
