It would be really nice to have a network (and web channel) endpoints similar to shows.
For example so you can hit http://api.tvmaze.com/networks?page=2 to page through an index of all available networks or http://api.tvmaze.com/networks/1?embed=shows to get information about a specific network (e.g. ID, country, timezone, logo, official website) and be able to embed information into it such as shows. Possibly even going so far as adding an ability to get previous and next names for a network and embedding information such as shows from those network names as well. I know the last would be a difficult thing to accommodate, but I think it would be a really nice feature.
