Still not working for me in consolidated layout with these settings. With the other layouts as long as notification center is on and show on lockscreen is on my mail will show up as a notification, but never under widgets.
Edit: What hardware and OS version are you using j4zb4? I have a 4S on 6.1, mail is obviously an issue but I'm not having your slider problem. Hidden slider stays that way though I'm not using slide gestures with activator. When the slider is hidden I have a small bar across the bottom of my screen, when I tap it the slider comes up. I also have tap the status bar to unlock set up in activator and that works fine.
Ok I have set it up as notification and show on lock screen... Also I am not using the consolidated screen... I rather prefer the notifications + widgets with notifications showing on lockscreen... Another thing I guess is that Email isn't set up to show as a widget... Even in LI4... The difference I feel though was LI4 didn't really differentiate between the two... Where as LI5 puts a clear distinction between the two...
About the lockscreen slider... Well it does stay hidden, but there is an option to show slider in lockinfo... Which I do wish to use... In the earlier version it was only by double tapping the home button.. In this version in addition to the double tap they have by default kept slide in from bottom botom left and bottom right to bring up the slider... Which I do not want... Not I deactivate it through activator and keep slide from bottom to unlock the device... But everytime it resprings it resets it to show the slider...
BTW I am running the same hardware-software... 4S - 6.1
