It would be very useful for the ideas section to be available at product line level as well as product and for it to roll up ideas from contained lines/products.
Where a product owner manages several products (in our case, a significant number of products) a single view of ideas to process and respond to saves a huge amount of time.
You can currently work around this by going to a product, into the ideas section and then fiddling with the filters... but this is rather clunky. Navigation to the ideas section doesn't exist at the line level and adding this would lesson the clunk.
Having the ideas overview etc... roll up ideas from its level and levels underneath with a context based filter would be an ideal fix and I would of thought a significant feature for idea management.
As noted, this is currently possible from the Ideas -> List page. You can set various filters and save the views (so that the views do not need to be created each time). We would suggest leveraging this view to easily handle requests across multiple products.
It's possible to create charts from the Reports->Chart page to reflect the additional visualizations shown through the Ideas overview page for products.
