Follow-up #725

To distinguish between all these types, we could add either the type's name, the first letter or the icon to the result list

1. First letter
2. icon
3. subheader

I think all 3 are an improvement, I don't have a strong opinion on which is best. So if you want to implement this go for it, and pick whatever you like best.

I will add one possible advantage to the third option is that it leaves room to add the engine labels on the right side as mentioned in #777
