[yocto] Hob 1.2 design - Settings dialogue

[Barros Pena, Belen]

Your verbose mode it's pretty helpful (as it happens with most verbose
modes), so please don't turn it off.

Answers below.

You guys are the experts. You tell me how you want it to work and I'll
design the UI for it! :)

Yes, the list will scroll at some point. I am not too worried about it
though, since I don't think that changing the image types will be
something users will do very often. I might be wrong though.

I don¹t know how the layer priorities work. Who sets those priorities? Are
they aligned with user's priorities? If they are, yes, we should use the
layer priorities to determine the order of that list of machines.

It is the case in the Image configuration screen, where users, before
building an image, select their machine using a combo box. This screen is
different from the Settings dialogue, where you set some BibBake output
and system variables (the image output types between them). This document
in the wiki 

http://wiki.yoctoproject.org/wiki/File:Hob_1.2_screens_inventory.pdf

might help making sense of the different screens.

That would be really useful. Is it easy to accurately determine how many
cores are supported by the CPU of the machine running Hob?

Yes, this probably makes sense. I'll add that to the document next week.
