The builtin pdf viewer has rather powerful viewing features, such as a grid view, that isn't even provided to such a degree by fullfledged standalone viewers. This is particularly useful for Beamer, where having an overview over tens of slides becomes cumbersome in other viewers, that at best allow a two-paged view.

Sadly, this functionality is bound to using the "windowed" mode of the internal viewer, which also changes the interaction between viewer and editor significantly.

• In windowed mode, focus switches from editor to viewer, once "build&view" is finished.
• Fullscreen mode doesn't work with multiple windows.

Desired behaviour

Access to grid view in the embedded viewer.
