This enhancement should not be extremely hard to implement and would have a
significant impact on usability of impress for presentations.

The slide 'swapping' or 'browsing' in fullscreen is much faster in OO 2.0 now
than it was in 1.1.x, however still slow compared to powerpoint. I mean the
delay when when the sandhour in the left bottom corner is being displayed and
when the next slide is being pre-rendered in the background. The trouble is, you
want, e.g., skip back 5 slides during the presentation to react on a question
from publicum and it takes just too long to get there. If you experienced such
situations you will understand, this is really a trouble.

I got already some nice proposals during last email conversation with HTH:

I think a kind of slide-navigation menu or widget could do the work. However,
one has to find some decent way how that should look like - a pop-up listbox
window showing +5/-5 slide icons or their titles (using UP/DOWN keys and ENTER
to select) ?

But implementing preemptable rendering could be efficient as well and might be
not that complicated. What about checking at least between every object being
rendered for a keypress and quit render process in that case ? Otherwise,
multithreading would be necessary.

Well, there's a context menu in slideshow now, that allows for quick slide

@cl: could you please take this over, I'm swamped currently.

there is the context menu, also there is the presenter consol extension for
multiple monitor support. Keeping this issue as a reminder that we can always be
