I think anyone who's used a vector drawing program or desktop publishing
program expects a group/ungroup action as a basic feature of the sort
of design program pcb is.

Yes you can switch off layers but since there is only one "silk" layer
I can't turn off logo/graphics/text/etc. while leaving element outline
silk turned on.

Not possible at this time -- the graphics are implemented using
polygons.  Now if pcb were enhanced (as recently discussed) to allow all
layout features (text, lines, arcs, polygons, ...) in footprints then
this would be great.

In case you were wondering, I am using imported graphics for much more
than just a logo. The graphics mostly consist of text such as board
name, date, revision, other info, "designed by" info, etc., as well as
adding a logo.  I find the pcb 'text' elements to be really poor from
both a readability and typographical beauty standpoint.  No offense
intended to the developers or pcb font designer since I know the current
font system simply has severe restrictions being built of lines only;
but by using Inkscape I can use the full Unicode character set and
a limitless number of beautiful and readable fonts.
