Glad you liked it. LMT is probably the first app I install after rooting any Android phone. Try adding a second layer of Pie for custom apps, or custom icons. I am yet to touch my sleep/wake button thanks to LMT. Theres so much you can do with it. Starting to sound like a salesman now
If you mean the notification on top of the pie, then just disable the Show Status Infos in the Settings tab
Or if you mean the notification in the status bar just longpress on it -> app info -> uncheck show notifications.
