Whither "Preview"
I have not kept up with the details in all Updates, and do not understand, (yet) the changes to the "Preview " item. It identifies itself as "Preview 5.5.3, and says it is "owned by NASA - Earth Observatory".
On my screen it has produced, without asking, odd items from the recent past, and one claim it makes is to be able to reproduce files without reference to the original software.
Is there somewhere I can read a description of the functions of "Preview" and how it can be useful (to me).
If you can also explain why Apple needs an Earth Observatory function, I would be grateful.
