About

I’d like to share Scroil, a utility I’ve been working on to bring fluid, natural mouse scrolling to Windows. The truth is, I’ve always found Windows scrolling to be... frustrating. Every time I switch from my phone or a MacBook back to Windows, the mouse wheel feels "jumpy" and inconsistent. It’s especially sluggish when I’m deep in a 2,000-line code file or a long PDF, and I find myself endlessly spinning the wheel just to move an inch. Scrolling on Windows can be better - that's why I built Scroil. Here're the main features of it: Features Global Smooth Scrolling: Brings smoother mouse wheel scrolling across your apps on Windows, reducing the jumpy feeling of apps's default scrolling behavior. Custom Scroll Feel: Adjust speed, step size, acceleration, deacceleration, and fine-grained scroll behavior. Scrolling Accelerator: Increases scroll speed during faster wheel movement, making long pages easier to move through. App Picker & Per-App Control: Add currently open programs to your Scroil profile list, customize scrolling experience for each app. Auto App Classifier: Automatically recognizes Chromium-based apps, including Teams, Discord, Outlook and others, then applies the right scrolling config for that app type. Game Detection: Recognizes games automatically and turn off smooth scroll for games to avoid interfering with your gameplay. I’m still actively developing it, so feedback and bug reports are very welcome! GitHub: https://github.com/EricxWood/Scroil Download here: https://github.com/EricxWood/Scroil/releases/
