Hey @AZ1 I am sure the Asana team and developers doing everything they can to implement as many features as possible which is also reflected in the regular announcements of new features that are implemented 
Here is a detailed overview of how Asana is listening to product feedback:
@Andrea_Mayer, this is getting some kind of joke. Users are begging already three years for this totally logical, obvious, nescessary and simple feature. Please tell us what’s holding you back. I would guess this feature takes about 2 hours to completely implement. We are your paying customers: please act as an service oriented supplier and schedule this request, let me see, next friday. Please confirm.
Hey @anon84562416 just to clarify I don’t work for Asana.
Regarding your comment I would like to refer to Bastien’s message that he has shared in another thread recently:
Sorry, @Andrea_Mayer, I didn’t know.
Hi, i have been having a problem, when i complete a subtask it is mak as “complete” but the subtask remains in my list view, It should vanish into “completed subtasks”.
I think it should show “1”.
Anyone know what language python is built on? Either myself or a friend can probably code the few lines this would take and post here.
+1 for this feature!
A WORKAROUND - not perfect, but still
Make sure all Sub-tasks are named clearly so you know what Task they belong to and section initially. Obviously, the history of the sub-task will show where it originally belonged to.
How has this feature not been added yet? I love Asana but it feels like the product team isn’t making many of the community-requested updates…
I completely agree Sarah_Lilly! We need to be able to HIDE completed subtasks! It’s been years in since the community has been asking this!
Painful.
Also, this is the kind of feature that can push people into paying for a subscription. Casual users don’t care. Power users need it.
Adding this request here and shocked this can’t be an easy fix. Are the Asana team listening?
Hoping that Asana Team considers this feature request asap - this would greatly improve workflows and “declutter” subtasks.
Hide and/or move to bottom option would be great!
End of 2021 and we are still waiting for this? It seems like a simple button to add (“sort list” must be possible, surely, on the backend) and yet still no progress. C’mon Asana, what’s going on?
Thank you for this workaround! Very helpful!
after 4 years still don’t have this feature??
We are desperate!!
please take this into action!
June 2017 and no implementation.
Also from my side, this would be an awesome addition to functions in Asana and makes working with it more comfortable. Why not just hide them automatically when filter is set to “Show only incomplete tasks” on the project overview?
I can feel it in my bones. 2022 is the year for this feature. Go Asana Go Go Asana! Now hide those subtasks! Now show those subtasks! Now hide them again! Everybody clap your hands!
