can we have some thing like ' grouping ' and ' changing sketch place ' ? I am using penpen as a notes taking and simple mind mapping tool now .
@benlau 'play all' button would be so awesome and would make this an app i would use if this was implementet I have Mypaint installed so the sketch thing for me is covered there Good job so far from you... keep it up
Zooming and Undo would be useful.
