Premiere Productions should have a nested sequence/project feature. Many people who are coming from long form into the new Productions workspace use nested sequences for each of their scenes. You should allow a master sequence within one project to contain nested references to sequences in other projects. These would be read-only unless you double click them to open up the original sequence/project.
As it is, Productions is cumbersome for keeping a master sequence of the entire show synced when you split your scenes into their own projects.
You should also allow the user to save a "Productions Workspace" which will automatically open all the projects that one wants to work with and arrange windows to their properly saved arrangement.
Productions would be 100X more effective with these updates.
We’re considering the nesting request, tracking that work as DVAPR-4223845.
We hadn’t heard the ‘cumbersome’ comment, but the feature film teams with which Productions was developed weren’t using nested sequences.
For the “Productions Workspace”: I think you can get that behavior today, were you to change Prefs —> General —> At Startup to “open most recent”, and then save a workspace containing your Production and desired one projects.
