This seems odd to me and doesn't seem expected. If I have a group with a triangle and a circle, when I dive select the circle and copy and paste it somewhere else, I would expect that object to be independent of the group. Not sure if other functionality is reliant on this behavior but I'd be interested in hearing why this is the case.
Actually it should only paste into the "edit context" that you are currently working in. Note the thick blue border on the group before pasting, if it's present then that group is considered the current active edit context.
So if you double click into a group, select an element, copy and paste it, it will be pasted into that group.
If you click outside the group first to make the pasteboard or another artboard the current edit context, then paste, it will paste there.
Gotcha. Thanks for the quick reply. I guess it's slightly different than a few other tools I've used but it makes sense. Very stoked with the product and looking forward to continued improvements.
