Ever wanted to see what your #GTK app could look like on mobile? Grab @purism 's #libhandy and open it in GNOME Builder. It will launch the demo app.

You can then play with the GTK widgets offered by libhandy, and change the window size to see how it looks like on desktop or on mobile.

It is feature-packed, try some gestures on a touchpad and you may be surprised!
