It would be nice to have a simple dialog like this:

-------------------------
----------------
| Show document |
----------------
----------------
| Save document |
----------------
----------------
| Close |
----------------
-------------------------
(Optional a button "Show options")

Because the default print/save dialog ist very complex.
The first button could create a pdf in temp-folder and show it with the default viewer.
Like http://www.pdf24.org/de/creator.html

In settings should be an option to select complex/simple dialog.
