This looks so interesting that I can't resist

The first thing I noticed is that libFilters has a few loops like this:

function(slot)                              
            local result = true                     
            for _,v in pairs(filters[filterType]) do
                if(v) then                          
                    result = result and v(slot)     
                end                                 
            end                                     
            return result                           
        end

These should do an early return, once any of the filters returns false, the result is final. I will send changes to Randactyl later; but this little thing can only cure some symptoms, not the disease (if the disease is filters accumulating in the list). So I guess I'll need to dig deeper
