It would be a good idea to be able to search by the TV channels/Network. If I want to watch all "OCN" dramas, then I can easily search for all the dramas aired on "OCN". Maybe make the name of the TV Channel/Network clickable in the drama pages, and it takes us to the TV channel search result page.
The networks' names are already blue/underlined on the drama pages, so they look clickable but they aren't. So I have assumed that this is a planned feature that's not yet ready to be used... I've been wondering about that, actually!
Definitely! For a while I have had to use other sites to find the dramas of specific channels (e.g. tvN). It would match well with MDL's other features - sometimes I want to find the most popular or top rated dramas of certain channels so it would definitely be very convenient, especially for people who enjoy dramas aired on e.g. OCN.
