When it's working smoothly, it's the best darn option on the market, 5 stars for sure. However, I've been having an issue where it will randomly stop fletching the bolts. It will still be clicking them, but they won't actually be fletching. In the top left it almost appears as if the mouse is hovering over other players. I have tried both fixed and resizable to no avail. This is with Broad Bolts.
