When you're in the same large-thumbnail view, you can swipe down with one finger to send a canvas to the trash, while swiping to the left with two fingers creates a copy of a canvas. The four sharing options - Facebook, e-mail, save to library, and Twitter - are listed as stamps, which you affix to the open envelope before swiping up again to share. When viewing the larger of the two thumbnail sizes of your sketches, swipe up with one finger to view the sharing options. Tayasui, which is Japanese for 'easy and simple,' embraces a flat hierarchy, which is really no hierarchy at all. Unlike Paper, you cannot save groups of sketches into notebooks.

Pinching in shrinks your current canvas to either of two thumbnail sizes, which you can then swipe to browse through your various works. You can pinch out to zoom in on a sketch, then you can use two fingers to hold and swipe to move about your canvas. You can swipe to hide and show the tools, and you can double-tap the eraser to erase all marks on a canvas to start over.

Swiping left and right with two fingers acts as undo and redo commands, respectively (and in settings, you can flip a switch to add small, unobtrusive Undo and Redo buttons in the upper-right corner instead).
