Thank you. I'll have to look into that. The last time I asked about doing something like that was when I told that having multiple copies of portable Calibre was the only way to do it.

Edit: Well I found some instructions for how to do this, set up a test library, and copy/pasted the command line thing, editing for my library path, but both the shortcuts still open to new test library. Is this something that actually works with portable Calibre?
