Using Quire as Backlog & Roadmap

Hi guys, I'd like to use Quire as a tool for collecting product ideas from team members. There're 2 problems for now:

1. I don't know how to collect ideas in a simple way, which doesn't require understanding Quire interface. In the same way as you do it on https://quire.io/feedback

2. Ideally, the backlog of ideas is getting grouped by team/metrics/modules and sorted by a product owner, and the most interesting ideas are being converted into high level tasks with dates, representing product Roadmap. However I don't see that Quire team is doing the same, could you briefly explain how you do that?

Another alternative I'm looking at now: Google Forms (simple input of ideas) + Google Spreadsheets (sorting the collelcted ideas, sharing the status, compiling into product map), however making hierarchy lists is not that easy in Spreadsheets, as here in Quire ❤
