All the new sign options look great, and i think a few different fonts to choose from would really top it off nicely.
Im building a slightly scarier build (as much as you can in this game) and all the happy clean round fonts just dont match the vibe im aiming for. A jagged handwritten or old english/blackletter would really change the appearance of my whole settlement.
Dont think we need hundreds of options, but a few different styles could make a big difference to designs.
