Something like this: Or really just any method of seeing what fish is currently hooked. I feel this mod would be useful when you're hunting a specific fish, especially during short time windows (like the pufferfish) or just avoiding spending energy on fishing for trash.
The game doesnt choose what fish bit until you pull in, the "hooked" message is internally just a "If the player pulls in now, get a random fishing result for this location and try and collect it" message, no actual fish is assigned until you pull in the line.
