I am a professional artist and I have had my Note 10.1 for about 3 months now. I have made extensive use over several years of Photoshop and Corel Painter with a digitizer pad under Windows. I have tried many sketching and painting apps on the Note and most of them are weak. By far the best are the "Infinite" apps by Sean Brakefield.
I spent 30 minutes last night playing with Sketchbook Pro, to help teach it to my wife. Question-- is there REALLY no select tool, to be able to select and delete out or transform only selected portions of a layer? Assuming the answer is no (that seemed to be the Google answer) my next question is whether its omission from Sketchbook is "on-purpose" because its not worthwhile for people who actually use it professionally, or am I right to think it is strange that it is not included?
