Make it so you can't paste more than the queue can handle with a number of keywords you can paste in. Right now, I have no idea how many keywords the queue takes and which ones it discards if I go over the queue limit, which is very frustrating. 
 
Please make the error in red. For example, "If you pasted in 135 keywords, but the queue can only handle 85 keywords, state a helpful update. Please shorten it to 85 keywords to continue." That way, we can more easily track what keywords we pasted in.
