This would be amazing to have. The way we plan is by phases since we use an agile iterative style method. So with the current implementation if one phase takes longer than we anticipated, we have to move each group individually so the schedule is accurate to project our end date.

If we worked and planned using a strict waterfall method, the current implementation would be fine. But for Agile, missing this feature makes planning difficult for more fluid development styles.

It looks to me that this is not a best practice of planning.
At least, that's what I have been taught years ago and always applied.
You still can set a milestone at the end of your group & link it with your first task(s) of the next group...

Why does this feature not exist?
It seems very VERY obvious...
Can't start production before i'm done with pre-production but both obviously have MANY aspects.
I see this was also recommended 4 years ago ... So not much correspondence or feedback from Teamgantt - Always a good sign :/

I agree. I just started using TeamGantt today and it's one of the very first features I went hunting for....apparently it doesn't exist yet...

I've been using TeamGantt for a while now and I'd find this feature very very helpful.

If you could create dependencies between groups so that when things in a project change you could move a group along the schedule and have the dependent groups move along also

At the moment you have to do this manually which is a time consuming pain as you have to reorganise every subsequent group in the schedule.
