Easy to miss toggles on the calculator

[Mendanbar]

Can we brainstorm some way to make the buttons a little more obvious in the hotspot shown? Due to the proximity to the OK and Cancel buttons, the toggles are very easy to accidentally press, and when they are toggled only a dimming is applied on/off. This makes it really hard for young or new users to the system to see, and it can often result in wildly incorrect bolus calculations.

Some ideas:

• Borders around the buttons (toggles and/or OK and Cancel)
• A more obvious on/off visualization
• Placement of the toggles moved to be harder to hit accidentally
• Confirmation dialog or some other mechanism to warn that the toggles have been pressed
• A lock icon that requires pin entry to allow changes to toggles or other advanced features
