A free mod for Stardew Valley, by GuiNoya.
This application is a zoom keybinding mod for SMAPI. It allows you to increase and decrease the zoom level by pressing a key on your controller. It also allows you to remove the limits or even increase the zoom level to the maximum.
The default keybindings are comma (,) for increasing zoom and period (.) for decreasing. If you want to change these, you can easily do so by opening config.json inside the mod folder.
To use this mod, you first need to have the latest version of SMAPI. Then, unzip the mod folder into Stardew Valley/Mods. Lastly, run the game using SMAPI.
