for the roadmap feature, you use product area but it's way too simplistic.
We need product area (ie business capability) groupings, and then "products" (to which we attach a feature). Using a custom field for "Tags" for Products isn't good as it's not consistent taxonomy so impossible to manage. Also, using Custom Fields Select type isn't possible either as you only have 50 entries for Select type fields - not enough. Please help us address that asap!!
