Hi! I just saw in the "What's new" for 0.7.9:

"A new toolbar button to choose/create different calibre libraries. Be careful using it if you also use custom columns."

Funny - I cannot find it (confused by the new layout perhaps?),
unless it is the "Restrict to" switchbox, but that was already present, isnt it true?

Anyway - I'd like to know also what exactly this button does, and which dangers lurk in the dark (as I <have> custom columns!)

thanks!
