1. On the preview of the task there's a number indicating estimated time for a task.

Is there any way to also add a 'time spent' indicator the same way.
I'd like to see time spent for a task without opening it.
If the question 1 has a positive answer, please consider the next one too:
2. Is it possible to show the 'already spent' amount of hours on a sprint bar the same way as 'To do' 'In progress' and 'Done' statuses estimations are shown in the top right corner of the sprint bar.
