Well, I don't really know anything about the grid system thing you're
working on, so I can't comment on that, but when I say smart resizing
behaviours, I'm imagining behaviours that support good layouts.
For example, if you want a row of buttons all the same width, you
could have a row layout container that distributed its width evenly
between the widgets inside it (in fact, I imagine that would be the
default behaviour, and similarly for column layouts and height). The
two columns in the camera settings panel could be set up like this.
You could even have a row layout container that found the widget with
the largest minimum width and made all widgets that width, giving nice
content-fitting behaviour while still keeping the UI neat.
I guess the question is whether widget positions, widths etc. should
be hard-coded or adjust to fit the widget contents. I get the
impression that you'd prefer them to be hard-coded?
