Let's assume that any change within this dialog applies the changes
immediately (reasonable with regard to today's computational power).

Uhmm, there are not-so-difficult cases on which this could not be
true. Suppose you have a complex document of a couple of hundreds of
pages with several images, tables, embedded objects and so on. You
then edit the default paragraph style because you need to change font,
but instead of clicking on "Liberation Serif" you accidentally click
on "Liliput steps" (common problem if you only have a touchpad), a
really wide (and ugly) font: if the change apply immediately then the
whole layout will be changed immediately, with all your images and
tables jumping to the following pages... writer could be quite slow on
complex documents and fixing this wrong click could take even minutes.
In fact I don't like at all the "apply immediately" paradigm: it could
be quite dangerous.

From my point-of-view, that can be easily solved ... if a document
becomes complex, or if the setting itself might have an unwanted impact,
then the system might delay the update until the user did not change
anything for XXX ms. Similar things are done within websites (e.g.
Google with their Instant Search).

For example, and if I remember correctly, the same has been done for the
new chart component. The "live view" is updated after 3 seconds ... Do
you agree?

Good point nevertheless :-) To me this seems to emphasize that some
reasonable description of the intended behavior is a must before
reaching out to the development.

Cheers,
Christoph



Good point about we need to describe what should be done. One idea would
be to have preview window showing the changes before they are accepted.
I tend to prefer delaying the change, if possible, until the user clicks
"OK". But if users are acclimated to a system delay before the changes
are implemented, it might work well if we select the correct delay.
