I love the long term time line view in Reports > Roadmaps > Features - particularly the way it can show the initiatives and goals at the top each release. It provides a great way to assess the impact of inserting more work into the timeline because it's possible to see what might be delayed or upset in the longer term plan.
If the goal's time frame appeared next to it's name, it would provide a complete view for this purpose, without having to click on each goal to see the detail. Ideally, I guess, it would work like the customisable features board and provide a selection of different fields that could be added to that view.
Thank you for your idea. One suggestion here would be to create a custom roadmap which includes additional details about the goals.
Given the flexibility on the custom roadmap and historical support for this idea, we are unlikely to implement this idea. We hope you can understand.
