Well, one idea would be to have the rectangle tool selected by default. If I want some other shape, click and hold, the menu pops up, select a shape, menu disappears. Draw.
> How on earth are you complaining about having too many options?
I did say in my post that borders would be a help, I think that's what you mean by "black outlines"? I don't want options, I want speed. As a designer, I'm aware of my options when it comes to visual design. I don't need to experiment with each one, I already have a decent idea what will work and what won't. What I do need to experiment with is user flows. For that, I need speed, not options.
> You do realize that it's a helluva lot of work to design responsive layouts
I'm aware of the work involved in designing responsive layouts, I do it everyday. One idea would be to design for mobile first in the wireframing app, then resize the screen, re-arrange the layout and press "insert breakpoint", then a snapshot of that layout would be saved. So the next time the screen reaches that width, the layout changes automatically.
