We hardly use Ideas. We work from portal posts, and we plan with the Roadmap field on posts. Since the switch to Ideas, we can't reach that field anymore: the idea drawer (Portal / Internal view) has no Roadmap field and no way to open the linked post in the admin, and the old admin post URL now redirects to the idea drawer. The only route left is to open a roadmap and use "+ Add new feedback", which takes extra steps for every item.
What we would like, in order of preference:
1) A Roadmap field on the idea that puts both the idea and its linked portal post on the roadmap in one step.
2) A link from the idea to its portal post in the admin, so we can set the roadmap there.
3) A setting to open the portal post by default instead of the idea, for teams that work from posts.
