[yocto] Hob 1.2 design - visuals

[Barros Pena, Belen]

Hi Joshua,

Thanks for the feedback. I don't have definite answers to your questions:
I think they should come out of a discussion between design and dev teams.

My first stab to some answers below.

I have no experience with GTK, but I would hope that standard widgets can
be themed. So the idea would be using toolkit widgets themed to match the
visual style. Is this assumption incorrect?

If no toolkit widget exist for a certain UI control, we have to either
replace it with a toolkit widget or create our own, but I really hope this
is the exception rather than the rule.

Nothing in the design should blatantly contradict the GNOME HIG: in
general they are good design practice and we wouldn't ignore them without
a reason to do so. If there are any exceptions (like the primary action
button one) we could look at them on a case by case basis. I don't think
leaving 12 pixels between the bottom of the window edge and the button
will make or break the interface. What's important is that the location
and spacing of those 'primary action' buttons are consistent across the
whole Hob. If we feel we shouldn't break the 12px rule, I am sure Mikael
will agree that the button effect is not that important, and that we can
lift it up to fit the spacing GNOME rules.

Yes, using the colours from the OS theme is probably the best thing to do.

It's a typo: sorry about that. It should say Hob of course.
