What does restart layout actually reset?

I'm trying to understand what "system->restart layout" actually resets...

For example, in the layout editor I set one of the layers to be initially invisible. During the game it's set to visible at one point, but when I call "system->restart layout" it doesn't reset that layer to invisible.

Does "system->restart layout" ignore the layout properties set in the layout editor? If so, which ones? And what's the best way to truly reset the layout - store all properties in global variables?

The layer is more of a global thing. When you restart it sets objects back to their initial states, and I think groups in events.

Layers and event groups are not reset to their default state. If you deactivated a group, it will stay deactivated after the layout restart.

All objects are re-created, except global and the ones with Persist behavior.

Hey Dop thanks for the response. Re: your comment on groups, just want to make sure I'm not misunderstanding something. Per the docs:

Restart layout:

Restart the current layout. Note that unlike Go to layout, this action resets all event groups to their initial activation state. Global variables keep their current value - they are not reset. To reset them use the system action Reset global variables.

?

Hm, you are right. I tested before posting that comment, but I probably put "Set group deactivated" action after "Restart layout", that's why it stayed deactivated.
