Version 2.14
Breakpoint handle on the canvas
Drag the right edge of any artboard to see the page between breakpoints, not only at 1440, 1200, 810 and 390.
Before this release you could only check the four fixed widths. Now every artboard has a handle on its right edge. Drag it and the page reflows live, so you catch the heading that wraps badly at 1000 before a client does.
How to use it
It is on for every workspace today. Open any site, and look for it in the place you would expect. If something feels off, reply to the release email and a person on the product team will read it.
