Great, that indeed works! Thanks for letting me know! The offered options are a bit confusing, though. I would have expected the two sheets on the green background to be copy but I didn't manage to figure out what they do? The icon of the blue button at the top right that seems to do copy is not something I'd associate with copy.
Regarding selection: with a trackpad it'd be great if it'd work without long press as you'd expect it to work on a mac. Being able to use the pencil to easily draw a select rect would also be nice.
Also it'd be great to support right click: Right click on a shape could open a context menu that would allow stuff like copy. Right click on an empty space could offer paste, create new shape, etc.
Also when I single click on a shape there is this button with two arrows at the bottom right. Seems that I can switch between two modes but I wasn't able to figure out what the difference is?
In anyway, that you a lot for this app. Is there a way to give tips?
