I quite like the update overall

but I'm not using the new home screen.
My only big annoyance is, as noted by several people, the loss of the little dots underneath books that indicated length at a glance - always found these quite useful.
Helvetica has always been the only one of the provided fonts that I like, however since we got the JB for 5.6.5, I'm back to using the font hack anyway

Plus they're fixing Helvetica in the next update, aren't they?
