Agreed also! Although I think any maps should just show the specific
"service group" for the train, i.e. only those services running West
from Stratford, or only those running East from Highbury and
Islington. The map that shows the entire Overground is too all
encompassing, and geographically challenged.

The trains aren't limited to particular service groups though.

All the dual voltage units can and do show up anywhere, NLL, WLL, DC and
ELL. It is only the DC units that are constrained to the ELL, (and the SLL
extension when it opens - and makes the map even more 'challenged').
