As someone with CDO, I find myself thinking WAY TOO HARD about my lock screen. I really do love the depth effect. In conjunction with some font choice, it really makes the lock screen seem composed, more like a magazine cover. It gives me a little jolt of pleasure to see it. BUT doing so eliminates the row of widgets and impairs functionality. Choices, choices!
Wish list (not complaints, just wishes): in slideshow mode, allow me to assign specific font choices or top-line widget to each photo. Or better yet, allow me to rotate whole lockscreens, each individually composed, some with widgets and some without.
I have set up some lockscreen/homescreen sets to be combined with custom focuses, and that works well. But it does require manual entering and exiting individual focuses. Which is of course exactly what those are for, which isn't what I'm specifically after.
(Oh, CDO? It's the same as OCD, only the letters are in the correct alphabetical order.)
