I'm running the latest Calibre on Mac.
I have two libraries - a very large one (~6500 books) on a NAS drive, and a smaller one (~175 books plus news) on the hard drive. I regularly switch between them; it can take several minutes to switch to the large one.
When you click on the Library icon, your choices are:
- Switch/Create
- Quick Switch >> otherlib
- Rename >> otherlib
- Remove >> otherlib
But this is counter-intuitive. The first, quick-switch, showing otherlib makes sense, but the other two
also impact the other library. You are renaming the library you are
not displaying the books of. And the only feedback I notice for the current library is in the title bar.
I suggest that Rename and Remove apply to the current library, not some other library.
