Notable Features includes:
1) Bucket Fill Selection tool with Tolerance slider for a faster way of painting.
2) [2-Tap] Paint : Users not being able to see properly the cursor during paint mode is because it is being covered by the finger that's doing the coloring. Users can use this feature wherein they could first tap on the place they want to start paint selecting or erasing, then do a second tap (plus hold and drag) anywhere on the photo to control and move the paint cursor. So being left-handed or right-handed doesn't really matter, you can prevent the cursor from being obscured when painting.
3) Blink Fill - shows the user what pixels are currently being selected or modified. Most useful when painting corners and borders.
