Fishing Rod Grip Toggle
This mod lets you toggle gripping the fishing rod, instead of having to hold the mouse button / LT the whole time. Optionally it gets rid of the camera shake during fishing.
Press the ‘menu down’ key to toggle the grip while you have a fishing rod equipped. By default it should be down arrow on keyboard and dpad down on controllers(?).
There’s an optional version that get’s rid of the camera shake while it’s toggled. You only need to download one of them.
