It seems to me that there need to be two sliders for Adobe Shape CC: the current one for determining sensitivity threshold is great, and a second slider for how fine/coarse the desired trace should be. There should be a way to edit the vectors within the app. It would also be great to be able to drag the file to the desktop from the CC library.
Thanks for the feature ideas.
Many people have requested the ability to add further detail to shapes and to be able to share them outside of Creative Cloud. I don't have details about whether the features will make it into the app, but I'll for sure be forwarding the request to the team.
