For example, in the board view in Asana, I can see all sections with their corresponding tasks in columns. Assuming each section is a quarter or month, this view gives me a simple but complete picture of the roadmap and features. I would like to have the ability of printing and/or saving as a PDF that same view, in one page, to share across with stakeholders. I know it becomes more difficult the more sections/tasks you have, so perhaps the ability of seeing X sections/columns per page would be good. The same applies to the List view, where it is fundamentally the same just sorted horizontally.
For the timeline view, an analogy would be to be able to print it / save it as PDF as if it were a Gantt chart. I want to communicate what we are planning to build in the year, the duration, dependencies, etc. The Timeline view is very appealing visually and would help stakeholders understand easily what the roadmap looks like.
Asana helps me to have a mental model of roadmaps and align on it with my closest stakeholders by sharing my screen or taking screenshots. However, it is disappointing that I cannot share it with a broader audience and instead I have to do some Excel/Powerpoint magic, which duplicates the effort and does not scale. My use case is centered around sections as time periods, but I think it could apply to other use cases too.
An additional thought, I think users could select which sections/tasks should be eligible to print or not.
