Blue is the color of the other wizards, but the createnet wizard needs to be
really redesigned to have a more consistent look before switching the color.

Hmm, I didn't think there were pre-existing separators, sorry.

Text entries have a 'width in chars' field which can be in glade. Even if it's
capped at 20, a user can still enter longer text, it will just scroll to the
right. 20 might be too small, so feel free to play with it.

Yes this stuff is tricky. Here's the jist
- For that particular case, you likely need to play with the horizontal and
vertical fill/expand settings for every element in the table. For example on
that forwarding page, try and make new elements use the same set of
expand/fill values. Generally you don't want anything to vertically expand.
Also check xalign and yalign
- For getting spacing right and for everything to fit nicely, really just
focus on spacing of containers like boxes, tables, etc. The main content of a
page should be a vbox, every chunk of UI will probably be its own box _within_
that top level vbox. If you add any boxes or tables, make sure their 'spacing'
value is consistent with the rest of the layout, usually 3 pixels for table
column/row spacing, 6 for hbox/vbox, and 12 for the global vbox.
- If you want to indent an entire chunk of UI like a table, don't tweak
spacing/alignment on individual elements, stick the whole thing in an
'alignment' widget, and use that to indent it all with one setting.
- Sometimes there doesn't seem to be any way to get an element to NOT expand,
like a small combo box in a table with a longer widget. You can shrink it, by
sticking the widget in a 2 item box, set it to not expand, stick an
'alignment' in the other entry, and have _that_ expand.
But as I said, don't drive yourself crazy with it, just make a best attempt
and I can try and fix up some of the weird bits as an add on patch. It can be
quite frustrating getting this stuff right.
