Hello,
In other 3D modelling and animation programs (for example Maya) there are the so called viewport bookmarks. You can add a bookmark with your current position and orientation inside the 3D viewport and later on you can easily return to the exact same position by clicking on that bookmark.
Does Blender have something like that? It can be very convenient in some situations.

here is an addon

I'll give it a try, it looks promising.
