1. Would be nice to have a special suitcase that you could fill with the fishing strings, hooks and etc. It should be equipped into the hand slot (traveller's bag alike) and equip your fishing pool automatically if anything breaks.
2. A special fisher's backpack should act as a fish stockpile storage (wheelbarrow). That way you could transport more wish back home. It fills with the caught fish automatically. You can draw fish from it by clicking on the backpack. You can unequip it and right click on the ground/wheelbarrow to unload.
