milek->af: OK, thanks for the explanation. I thought that issue 43354 is related
because it would make possible to reuse the previews stored as thumbnails in
template files, and that would mean at least some caching, so this should work
faster. I don't know how fast but judging with the command line tools, I'd say a
lot faster - it took 3 minutes in OOo and something like 15 secs in the command
line to unpack the previews with 7zip, rename them, and put into a directory
(for the same set of 40 templates).

The previews in "Used in this Presentation" and  "Recently Used" lists are not
such a big problem as these lists are always shorter. Nobody would dream of
having 100 master pages in a presentation whereas one could easily have hundreds
of templates.

Of course, it's possible to solve this problem by creating some universal cache,
like a set of image files and parameters (names) stored in an xml or even text
file (or binary one for speed). But that would mean unnecessary discarding the
existing previews from templates, IMHO, as the thumbnails have been already
created so why should we create them again? Anyway, XML + images could be a way
that could be also implemented in an extension: the extension author could
create a preview and store it in the file, so that OOo would simply read the
cache and display it. But this kind of universal solution is much harder than
simply reading the existing thumbnails from the template files.
