The most important part of any drawing application is arguably the drawing area, so we've just made Sketch contain one big and infinitely large view with no palettes to be seen. That doesn't mean we've compromised on the tools though. Sketch is a true vector editing application and has many powerful tools to manipulate those vectors.
Sketch has boolean operations that fully preserve your carefully constructed vectors down the individual curves. For optimal flexibility we have something unique; dynamic boolean on groups of vectors. But there is more; Sketch has distortion tools as well as transformations, scissors and your truly innovative Smart Rotate which makes consecutive rotations truly easy and intuitive. The vector tool itself is intuitive and easy to use and our pen tool is an excellent starting point that produces really smooth curves.
