Retroplanning using GannttProject

Hi,

I’m new to GanntProject, and can’t find a feature to ease the creation of a retro planning, or more specifically the " Schedule From" feature one can found in MS Project. Did I miss something ? I tried to fiddle with schedule options (start date calculated) but did not find a way to easily modify task duration without affecting the end project date.

Thanks for your help.

Oh found this How to schedule project tasks based on an expected end date

Unfortunately the link is going to 500 server error.

Both this link and a link to GitHub issue from that page work fine, at least at the moment of writing this.

Indeed. That was temporary. Sadly I’ll have to switch to another software. Thanks anyway !
