Well, your point is to use a BonoboControl for displaying all this. Let's
assume you have a dir with 30 different files in it. I don't believe it's
very efficient to start multiple controls to create a preview for all the
different file types.
My idea is to define a standard way of storing such previews on the
filesystem level. If we provide some helper functions for managing these
an application can create a preview image together with the original file
during saving. Then write a bonobo control which reads the thumbnails from
the filesystem level.
At least the Gimp developers consider these mechanism too. And it's also
open for non-Bonobo applications.
