I think it would be really cool to have an item that lets you zoom into an area and accurately ping a location within its focus. Often times when the crew and I sail around exploring, one of us will see something interesting and will try to ping it so the others know where to look. With the current system, you have to open your map and make an educated guess where to ping on your map. In my experience, the pings that my fellow vikings (and myself) make for locations we see in the distance are, more often than not, inaccurate. An item that lets the player have more control and accuracy would be a must have for any would-be explorer.
It would make the most sense to me personally to have it be crafted out of Fine Wood, leather scraps, bronze/iron nails (can vary depending on when the dev's would want such an item available to the player), and cryatal at a high level workbench.
The cartography table was a game changer for me personally, and I think the addition of something like what i've described would compliment that style of gameplay well and make exploration even more rewarding and engaging as a style of gameplay!
Anyways, to the devs: thanks for the wonderful game that I managed to sink almost 1k hours into. Here's to the next 1k i'll inevitably put into it!
Skol!
