Closing the thread means “we won’t do it”. Asana is not saying they won’t do it, for all we know they might be doing it right now. They just simply don’t communicate the roadmap. And they do revisit those feature requests often. So I am hopeful.
If this is the only thing keeping you from using Asana, I hope the next tool you pick will have everything you hope for. Most of the competitors we looked at don’t have a public roadmap either. And they don’t always do what the community is asking, even if they do for years.
