Thanks for the hints with the theme switching, I'll try them out.
As for the minor theme modifications. I experimented a bit with having
an environment variable
with buffer properties (which was not working well) and with the
following (in my init.lua):

function set_buffer_properties()
  local buffer = buffer
  local c = _SCINTILLA.constants
  buffer.zoom = 1
  buffer.indent = 2
  buffer.edge_column = 80
  buffer.edge_mode = 1
  buffer.margin_width_n[0] = 4 + 3 * -- line number margin
    buffer:text_width(c.STYLE_LINENUMBER, '9')

events.connect('file_opened', set_buffer_properties)
events.connect('buffer_new', set_buffer_properties)
events.connect('view_new', set_buffer_properties)
events.connect('reset_after', function ()
  for i=1, #_VIEWS do
    gui.goto_view(1, false)

The last function is only necessary to have changes applied in all
views. Just like the function in the language modules
"set_buffer_properties" could be used for global modifications without
having to change the theme files.
There are some modules that require changes to the theme, multi-edit
and line wrap, and there have been quite a few questions on the
mailing list how to do minor theme modifications. Maybe this could be
the way to get this functionality, maybe an empty function could be
added to the user init.lua when it is created.
