Many times I want to switch positions to objects (especially lights).
This compound is pretty trivial but useful.
You have 8 objects (you can add many more by just copy pasting, but I stopped at 8), and you have 16 positions you can  put those object too (visually on screen) as bookmarks, like you do with billboards.
You also have time transitions (from current position to new position).

There is also a global selector. If you press 1,2,3,4... etc it selects the corresponding position to all objects.

Of course you can create presets with all sorts of combinations and screen setups.

Hope it helps.
