Not exactly as this but I think the idea behind tooltips is quite similar it's
just for things bigger that just a line of text. (We *could* as well use
tooltips but maybe that i a bit of abuse).

Well I'm just that kind of person ;-) I prefer click-to-focus and double click to
open(in file managers). But as no further interaction with the selections aside
from preview and select is possible i think this shouldn't be a big problem.

I don't see why we need to preload the previews. At least with pixmap based
previews my parents P133 has no trouble to load moderatly(say 400x300) sized
images without much delay. Modern (and some years old) harddisks are fast.
With previews that really use the theme (i.e. not pixmap based) I'm not
competent to say how much time it takes to get the preview on the screen,
but it would be quite nice if that would work (at least on high performant
machines), too.

Old browsers, slow internet links, latency in network operations...

I think this discussion would need some hard facts, maybe someone (or even me)
should implement a test program to see how it works out in reallity.
