The General preferences contain settings that affect the behaviour of various aspects of Sketch.
If selected, the macOS feature Auto Save will automatically save your Sketch file regularly so it can be accessed, and reverted via Versions.
The pixel fitting option will round layers to the nearest whole pixel, and ensures objects don’t sit on fractional pixels when drawing, moving, or resizing.
Should PDF and EPS files by imported as ‘flat’ images, or should Sketch try to interpret the path data inside them and make the shapes editable?
Allows you to define the order in which Artboards will be exported as PDF. Choose between Layer List orders; top-to-bottom, or bottom-to-top—or in reading orders for various locales.
Should Sketch Mirror always update to show whatever Artboard you have selected on the Mac or should it operate independently?
