Allow for comments and notes

The game is complex and it would be great if you could add "notes" or comments. Maybe allow for "pins" on the map so players can map out and comment their factory. Would be great if these are searchable too. E.g. "sulfur production" maybe with an icon on top. If I now need to find my sulfur production I could search for or add comments like "needs refactoring".

There's definitely a need for something like this. The ability to add notes on the screen or on a specific structure would be great.
