Voilą, it's all in the title.
It doesn't do much good, but it's pretty.

Seen as caliber manages the folders that it uses for the librarys, I don't think that evening a difficult feature added.
In attachment files the .ICO and the desktop.ini I use for my librarys.
In any case, a big thank you to the caliber developers

Is a powerful software that I use every day
