A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
Nope, other than the fact the quotes annoy me, also, I would like an option to disable the emergency mode.

Describe the solution you'd like
I would like to be able to customize how the block screen looks, I want it to be more of a clean simple screen that says "You've used this app long enough" or something simple like " is blocked"
