I'd just share a two suggestions that came to mind today, which might be quite interesting and useful.
The second being a bit harder, I believe, than the first one.

First
A marker for a Beefalo saddled by you, not showing the ones Saddled by friends.
On an added note, I'm looking for (or thinking of someday making it, if and when I ever learn to mod for DS/DST) a mod that makes the Beefalo not drop the saddled but have a way to manually remove it if you wish so.

Second
A widget that allows players to turn on or off markers manually, such as the one in the "Waypoint" mod.

(On an added note, I really like the waypoint mod but it really hurts me that it is client and not Server. Any possibility of adding a function like this to Global Positions if a Widget such as this does indeed sound interesting?)
