Hi there guys!

love your app, specially for ipad! you did a great job, specially for artist like coming, how coming from the SAI/ps background. really i'm in love with artstudio pro!.

here is my suggestions to improve the workflow:

-Warp tool with Transform ( also, using transform, i don't know if is just the ipad version but works very slowly)
-Bluetooth support: because a lot of artist still use basic functions like cmd+z, alt for color picker and adding different actions to the keyboard to make quick stuff.

-left handed support: just the chance to move some panels from one side to another, nothing crazy, a change of sides will be great!. ( im lefthanded so u.u )

-chance of change the color of the UI or typo ( some artist works better for example, with a white background, I personally prefer to have a black one! gives you better contrast on your picture )

-Channels : because is used for masking, color variations, etc.

-Liquify ( ok, maybe i'm asking so much u.u maybe this one is not 100% need it )

Keep doing the good job!
