First, iPad users can leverage another Sensei-powered tool: Object Selection. This particular feature was only added to the desktop app in November and the company worked quickly to bring it to the mobile version. Essentially, Adobe's AI and machine learning will automatically make a selection for you beyond just the main subject. If you don't have time to use the Magic Wand, Lasso or other selection method, Photoshop can do the (often time consuming) heavy lifting for you. Select Subject is handy when there's a primary person or object in an image, but Object Selection will offer something similar for more complex files.
Once you pick the Object Selection tool, you simply draw a rectangle or lasso around the area you need to select. Photoshop will find the "primary objects" in the highlighted area. You can also add to the selection by continuing to lasso other parts of an image.
Adobe added type settings to Photoshop on iPad, too. The company says "many of the typographic controls" from the desktop version are part of the update. Those include type layer, character and options properties. This means you can adjust things like tracking, leading, scaling and formatting (all/small camps, super/subscript, etc,). Kerning, a key typographic adjustment for designers, won't be available until a "future release."
