Hi Delphine,

Unfortunately there isn't a way to just view them inside the Gantt schedule itself, however if you make all your critical path tasks into milestones you can go to visualizations and see data regarding only them on our Project Milestones dashboard. Here you can see a calendar on which days they fall, a timeline, and they're completion rates. Hope this helps, let me know if you have any further questions. 

Kind Regards, Sophia 

Hey Delphine,

Yes of course so if you look to your left toward the bottom you'll see a little gray line graph image with the word Visualizations underneath it, although I'm assuming there's a french word for this I tried google translating it and it didn't show me anything.

Once you click on this it will load multiple dash boards look for the one called (jalons du projet) that's where you can access this data. 

Also if you need help creating a milestone just double click on any task you'd like to mark as a milestone and it will open up the task properties on that first page they'll be an option to check it off.

Keep me posted on if your able to find it or not or if you need any additional support.

Regards, Sophia
