I am looking for a very simple thing. I want to create a polygon based on the current view extent of my project.

In fact I want to

1) open google satellite layers 
2) zoom to my area of interest
3) create a polygon based on the 'view extent'

of course, the GE layer is not important, it should work with any view.

Sounds like spatial bookmarks - maybe that's also an option.

But given that you have a current polygon layer in the same CRS as the project, you can do this in the python console to add a new feature with the current extent:

   f = QgsFeature()
   f.setGeometry( QgsGeometry.fromRect( qgis.utils.iface.mapCanvas().extent() ) )
   l = qgis.utils.iface.activeLayer()
   l.startEditing()
   l.addFeature(f)
   l.commitChanges()

I have found the optimal answer (sorry Jef, I started digging into the python console, and will continue, but this one was quicker).

The QMarxan plugin allows for creating a grid from the view extent.

thanks!

QGIS 3.10 introduced 2 new tools (or maybe in earlier versions). With it, you can convert layer features to bookmarks or vice versa:

Convert layer to spatial bookmarks

Convert spatial bookmarks to layer
