Better Fishing allows you to Fish and Hook with a single keybind. It uses Dragonflights new Soft Targeting accessibilty feature which lets you target NPCs and Objects (the fishing bobber is an object) with camera only and use the Interact key to interact with the target. This addon combines the features onto a single key. Double Click (with Right Click) to cast is also supported but has to be enabled via options (/bf or /betterfishing). Go to Settings > Keybindings > Better Fishing> Cast and Interact to set keybinds
Combine it with my other addon Speedy Autoloot for a seemless fishing experience https://addons.wago.io/addons/speedy-autoloot
