K4kadu/BB-Shader-Display — reverse-engineered prompt

Build me a small Love2D desktop tool for previewing fragment shaders while I’m editing them, mainly for Beatblock custom level shaders.

I want to keep the app open next to my code editor, pick a folder that contains shader files, and have the preview update automatically whenever I save changes. It should be able to show the raw shader output, or show it interpreted and recolored like Beatblock does. Add a simple settings area with an open folder button, and an option to keep the window always on top.

The preview should use a fixed internal resolution of 600 by 360 with no anti aliasing. Please support shader uniforms for beat and time, mouse position from 0 to 1, an angle value controlled by mouse input like a crank, accumulated mouse scroll, and resolution set to 600 by 360.

Keep it practical and lightweight. If you need details about current Love2D shader APIs, look them up online.
