I'm wondering if there is any way to create an entity/whatever that will appear on the world map like the entity destroyed, entity damaged, and defenses engaging the enemy alerts do. I don't care if it appears by the hotbar (would be nice though) I just want to be able to open the world map and see my map marker. Ideally it would appear for 10-20 seconds before fading.

Any way to do this and if so, how?

Yes.
You can use dummy station entities to create markers on the map. Sign-post mod does that, some others do too.

Ah. I was poking about the lua docs trying to figure it out. Thanks. I'll download one of those and figure out the details.
