When I cast Inspiration on a city two more line items appear in the detailed research info for the city:  Inspiration +2, and Inspiration (10%).  This is great, it lets you know exactly what effect the spell is having.

When I cast Enchanted Hammers (EH) on the city it can be hard to tell it is doing anything, as the bonus of +2 per Materials is just folded into the main line with no extra details provided.  I actually had to cancel the spell and recast it so that I could be sure it was working at all.  Please change EH so that it displays information in the same manner as Inspiration.

Possible Example:

Production 20.4

+0.1 per Population (17)     +1.7

+5 per Materials (3)            +15

Enchanted Hammers           +6

Unrest (-10%)                    -2.3
