Recenter scene when the image is empty

[ghost]

Is your feature request related to a problem? Please describe.
Sometimes while navigation with a mousepad or mouse we lose view of the cones and edges and it may be difficult to view them again

Describe the solution you'd like
a command that would recenter the scene, or even better maximising the view of the elements in the window

Describe alternatives you've considered
for the time being it is faster to reload the page and drag and drop the files
