This comes from a project management use case where a team manages a set of activities/tasks through Features for a project and the activities have a very sequential delivery with fixed offsets between each activity. The plan starts off with loosely defined dates and dependencies between each activity. For example, Activity 2's due date will always need to be offset to complete 2 weeks after the scheduled due date of Activity 1. As the Activity 1 due date is solidified and updated (pushed out a week), the desire is that the week 2 activity would automatically push out by the 1 week to maintain the desired 2 week offset in due dates.
These dependency relationships will be maintained IF you modify the dates via drag/drop/stretching on the Releases -> Overview/Roadmap page. However, if you instead modify the dates in the drawer page, it will not shift the downstream dependency activities/features. Instead, any violations of the Finish/Start dependency relationship are highlighted in Red but all downstream Features/Activities maintain their previous dates. .
Desired behavior: Ability/option to have the downstream activities/features start on and due on dates to adjust when modified in the drawer page. Admittedly, I can see where you might not want date changes to automatically push out downstream dependencies as you may want to instead view the changes and collaborate on them as a team to decide whether you want to push things out, reduce scope, etc. However, in some instances when you have a team managing a very large number of projects, they want to be able to automate as many processes as possible and minimize manual rework. Having the option to make automate these dependency related dates regardless of modifying in the Releases Overview/Roadmap views or in a drawer page would be ideal.
