Good idea, it would indeed be helpful to have some more filter options, like this one.
However, this would not consider workflows that are not active but are used as sub workflows.
I usually simply use the tag functionality to make sure I can find workflows easily later.
If you are not using that already, maybe something to look into.
Appreciate the response, and yes I use that but just thought in a moment when doing an audit of my workflows that it would be a small qol addition. Thank you!
