Sup thanks for using, I added a setting under Notification Settings to anchor them to bottom of screen thanks to you:

...then I will work on adding the slider and fixing the button positioning (but don't expect to be completed some time soon because I recall it took many hours to look great before the unfortunate reset)

EDIT: The button positioning is fixed

EDIT: I added a Toast Mode which when combined w/ Anchor Notifs, centers/shrinks them to bottom like this: https://i.imgur.com/K9xMgEV.png
