Randomise appearance and mechanism for setting intervention time

I absolutely love this app for taking a second to reflect before opening a blocked app, however after a few months my brain has gotten so used to how it works that without thinking I will:

Open a blocked app

Check notifications while I'm waiting for the timer

Move the wheel to the maximum time

Open the app

It would be nice to have the mechanism to set the maximum time before re-intervention change each time, so that it forces my brain to think a bit more to provide more of an obstacle to opening apps
