What would be good is if you could see your catch report for the current session while you are playing. Just an option in the menu to see all the fish that you have caught with weights and stuff. Also maybe add your total TP in a corner somewhere so no need to leave the game/lake to see how many you now have.
Like the sound of that also would be a good idea is when u loose a boss fish be great to know which boss fish u lost as it would give u an idea what bait to use or not use next time u try to catch that persfic boss fish
