Sometimes when you make 10 - 15 items or inventory spaces of the same item, it seems a little tedious to then have to move them one at a time to the sell window.
This is annoying, especially if you're trying to work on something like weapon smithing and you have to add 15 or more items one at a time.
I think an option where you could right click on an object for example a throwing knife, click sell all or select all and all the throwing knives in your inventory are automatically added to the sale window, would definitely be a very handy option.
Sorry if this has been mentioned before but I looked briefly and haven't noticed it anywhere and thank you for taking the time to review my suggestion,
