I'm not sure if this is in oldschool but i do believe it is, I also have not found any suggestion for this.
Anyways back to the suggestion, like the title say's. The option when fletching to be able to choose an (All) or (X) option would be a nice addition to the game. Fletching can be so time consuming and boring when you have to look over every 2 seconds to do another 10 sets. It's more of a convenience thing. If you had the option to use All or 10 at a time, which would you choose. Don't get me wrong though, I'm not saying that you make 10k at one time, just that you don't have to click items again after a set of 10 is complete.
That is my suggestion. Please leave a reply with your support or reasoning for not supporting.
Thank you,
