How can I have a unique Task ID visible in Asana. I was looking for such a field, but I cannot find it.
I cannot believe that Asana would not have the functionality for a (autogenerated) Task ID wich can be displayed in a list and to which we can search on.
I recommend upvoting the feedback request thread that I shared.
Also something else that might help is enabling row numbers via settings in case you have not done so yet. I know this is not what you asked for, however some find this helpful.
As it stands yes. However Asana is constantly monitoring all feedback request threads (total views and votes) and they implement new features regularly, see the latest ones here.
