1) It would be nice to have a link to the official site at the Network / Web Channel page. Especially for Web Channels.
2) Ability to manage Web Channels list somehow (at least possibility to sort it alphabetically / by number of series).
3) Search among Networks / Web Channels.
For the time being the only way to quickly check if particular Net / WebCh exists is to look at the list on the "Create Show" page. Which is a bit inconvenient :)
