School specialties are not differentiated

[Lilith-Palmer]

Whilst using the map, the filter allow users to sort schools via 'specialty'. The issue is that there are a large variety of specialties that can be very different, but they are all bunched together. This is not particularly helpful to users. Once they have selected the filter, they still have to hover over each school to ascertain it specialty- which is time consuming, especially if they are looking for something in particular.

Perhaps adding a second layer to this filter, that enables users to select one specialty would fix this.
