E - Signal
Data ping / API signal. Three arcs + a dot. Ties to the live radar on the map. Developer feel.
F - Skyline
Three buildings = business entities in a city. Instantly readable. More visual than any other option.
G - Search
Magnifier with data lines inside the lens. "Look up any business record." Direct and functional.
H - Filing cabinet
Two drawers with handles. Most literal to the name "FreshFilings" - what the word actually means, made visual.
