RATIONALE
During face detection especially, but also for tags and albums, I would like to be able to zoom into thumbnails.
Quite often I see a face which I have tagged but I don't remember the name of that person, and so I search for the image in the sidebar. To do this I have to zoom in to make the thumbnails recognizable - but zooming in also reduces the amount of faces visible in the sidebar tree.

I would like to be able to *temporarily* zoom in (i.e. enlarge the thumbnails in the sidebar) e.g. by using CTRL+scrollwheel to find a face, then quickly reset this to the original size again.
An alternative would be to have a larger thumbnail (at least 100x100 pixels, so that you can recognize the face) show when hovering the mouse over a face thumbnail.

This would make finding faces with unknown names much easier.
Thank you!
