Sometimes we forget to deactivate our Good books right? Why not add an option that toggles them on and off outside of combat or skilling within a set amount of time.
For example:
[Toggle Auto]
Upon skilling or combat, the books activate.
5 minutes go by....(no skilling or combat)
Books Turn off
Saves players from forgetting to deactivate their books, then being frustrated because they forgot.
I'm neutral on this, but if they were to add it, they should add it for other items as well - scrimshaws is the item that comes to mind for me, but I assume that there are other items that could use this too.
Things may be looking down now, but I see a light at the end of the tunnel;
Do you think I should get off the tracks?
I completely forgot about scrimshaws haha. Or they could add a notification or reminder to your screen that tells you that your books/scrimshaws are still active every 5 minutes or so.
