"another use case of mine is when I don’t know exactly what overload for a function I need until I try some of the"  That is exactly the same in my situation. You can check how PlayMaker organize that things .  You can open one category and have it open all the time to jump between different action and testing it . 


Yes fuzzy finder window need work , its basic . Puting tons of action from similar category is very time consuming. Maybe if making window docktable is to hard for you at the moment  you just can add a option to keep finder on the same "page " category for example  even if you will disable window for the moment .   That will speed up work a lot
