Just something I found out by accident:

Open a book (or jpg)
Click the little clock on the bottom
click it again
and again
now close the clock window.
clock is still there
close it again
and again
clock window is gone

obviously it's possible to run several instances of the clock on top of each other.

I wonder how many of them you can have runnning before the reader crashes :-)

Would be nice to be able to open two books at the same time and switch between them instead.
