Hide completed subtasks

I actually wonder how many people even really know about that feature considering this here - Display subtasks on List view when project is filtered/sorted

If people are always working out a project that has a saved filter/sort, they probably can’t use this workaround as most people do prefer filters/sorts (like hiding a subtask when it’s completed) over dropdowns. Which, I assume many people are, so many wouldn’t even see this as an option, and I mean literally, since the arrow it gone with a filter/sort applied. I really just don’t feel like for most people this would be viable, but it does work great otherwise. I don’t think it should be considered a solution though.
