Is it possible to implement a "Naming" feature of factory buildings? That instead of reading "Factory Building (inactive)" on inventory we could read something like "Lab Factory (inactive)" and also in the world it would show the name when you mouseover the buildings. A feature similar to the mod Free Real Estate which is an alternative to factorissimo1 mod.
This feature is planned, but delayed to 0.15 for various reasons. In the meantime, might I recommend the factory display overlay technology? It lets you put icons on your factories.
