editor has modes of display like finder

4.18: adde/editor has modes of display like finder:
. the editor has modes of display like the mac finder does;
an editor's usual state is large icon mode,
where you choose how the text and image panes are
tiled together in a layout .
. the other views relevant to an editor are:
subtitles tree, listview of panes,
and any number of other customized layout views
for adjusting the #columns and paging length
to fit the various window dimensions
(1024x726, half, quarter, ipod-sized ).
. the small icon mode makes it easier to do
layout changes from a bird's eye view,
seeing several pages at once .
