As a UX designer, I want to copy as an image the selected widget from mockup and insert it into documentation, so I don’t need an external screen grabbing tool and increase my productivity.
Currently Balsamiq allows to get PNG image of the entire mockup (
File -> Export -> Mockup to Clipboard or
CTRL+SHIFT+C). But for documents I frequently need just a widget or even a fragment of it. So I use external screen grabbing tool to copy some fragment of the mockup.
The lack of it isn’t a huge pain, but having this feature creates better flow (as described in Kano model), is a delight!
