Hello,
Thank you for your answer.
OK, I didn't know this functionality. Is it possible to select many activities with a shortcut (Shift, Ctrl...) ? Selecting hundred activities means 100 clicks...
I was looking at it in Follow-up / planning and not in Work / activities, because it's easier working on the planning view with indentation than in the Activity view where it's difficult to work with all activities at the same level.
If you confirm there's no such icon in Planning view, I would have two sweet dreams

:
- either adding the functionality in Planning mode
- either indenting a little in Activity mode
Iin fact, I realize that I'm wondering why there is 2 different views :
- the left panel of Planning mode (very legible and for me the main work area with PrOjeQtOr)
- the Activities view (not very legible in my humble opinion) which seems to me offering more or less the same functionalities
Sincerely.
