In the micro planning view, I would like to be able to duplicate a task, ideally by right-clicking from the task list (where we have the handle to move the task up or down in the list), or even in the card when editing the task (next to the trash can to delete it)
Yes, feasible. Added to backlog
Hello @Valerie_LEHMAN ,
It’s live 
You can now duplicate a task directly from the Gantt view, exactly as you imagined: right-click in the list (at the drag handle level) and voilà, it’s done.
A big thank you for your suggestion 
This is typically the kind of idea that moves the product forward for everyone and perfectly illustrates the spirit of the SUIVI community 
See you soon for the next developments!
