The problem is that you suggested something extremely close to something that already existed as Pen illustrated. This means that it will be less likely to be made to your specifics (what DOES from the Suggestions and Requests forum?). What I did was keep it similar to each Add-On, while making it a bit more original and appealing. I like the idea of hotkeys for ascending and descending, but I doubt a notable amount of the Blockland community would be competent or patient enough to memorize controls for a specific item, while others would see it as a waste of keys on a keyboard. I'm not even sure if you CAN "combine" the two, but I'd totally use it if whoever made it did it right...
