The tooling isn't the problem, time is. Every device and resolution you support takes time and at some point you hit a point of diminishing returns.

If it takes too much time, you are probably doing something wrong like having hardcoded layouts for different resolutions instead of using reflow as much as possible.

Even with all reflow it's hard. Should I reduce a width a little bit more so that it become 3 columns instead of 2 on iPad vertical at risk of having some line wrapped? Things like that.
