Thimble is an extension for macOS that allows for customizable functions in apps like Photoshop, Sketch and SketchUp. It is designed to accelerate work in these apps and more with the use of multi-touch. By resting your thumb on the trackpad and scrolling up, Thimble is opened and offers an alternative to mousing across large screens that can eventually cause fatigue during long sessions or clutter screen space on smaller monitors. Thimble is great for those who continually need to access menus and can streamline and simplify work with customized gestures.
