I wonder, why it is not possible to change the width of the designer canvas anymore. Means, grabbing the border between the right toolbar and the canvas, to check, how it is working in smaller views, is not working anymore. It is just affecting desktop view and was working until some days ago, at least.
I hope, this is just a temporarily appearing bug and not a feature
Btw. it would be great to have sth. like a handle at the right side of the canvas in desktop view, like in mobile views, as it was never very easy to grab this border.
