Thank you for the reply Peter,
For the second point, this is expected in a future release? (I see the feature in the Scheduler component, but it would also be interesting for the Gantt, for see the different scheduling like programmed date and the real duration with possible delay(a second task row with the delay)).
For the third point I use the non-working days but the property change all the column of a day, not the single cell of a day of a task row, it’s correct?
Thank you.
