Help with widget placement.

Froglord1

I'm making a widget for a status effect which needs to be visible no matter what screen you're in. (Management, no screen) The effect is triggered by using an item, which causes the widget to only show up in the management screen. I also want to be able to see my custom health in the management screen without a custom toggle or button. Thanks in advance,
Froglord

Also, if possible, can you tell me a way to make the player stop if you open the management screen. I could probably do it with enough time, but it's always easier to get a quick answer.
