Wrting a new plugin is often trivial.
Just create a new `channels/name.py` following this structure:

    # title: MyPlugin
    # description: my radio list
    # version: 0.1
    # type: channel
    # category: radio
    # url: http://www.mymusicstation.com/
    # config: -

    from config import *
    from channels import *

    class myplugin (ChannelPlugin):
        title = "MyNewChannel"
        module = "myplugin"

        has_search = False

   * With a `datamap=[]` declaration custom field names could be displayed.

   * Often you just want to rename the column titles however - per `title=dict(listeners="Whatever")` in the class declaration.

Received station lists get stored internally in a `streams={"Pop":[...]}` dict, and cached in the `~/.config/streamtuner2/cache/` directory of course.

There's also a `config=[]` list, in case your plugin needs to keep some settings. (For example an API key.)
You can access your <kbd>config:</kbd> options per the global `conf.*` dict. Take care to prefer unambigious names like `conf.myplugin_pagesize` etc.

The `has_search` class flag permits live server searches. If one is issued, the `update_streams()` method will be called with `cat=None` and `search="Find me maybe"` set instead.

  * Other class options include `listformat="audio/x-scpls"` for declaring the station URL mime type (here `pls` for example).
  * And `audioformat="audio/mpeg"` for the audio mime type.
  * While `current=""` and `default="Pop"` can specify which category is visible per default, or currently active. (Both will be retired in later versions. More a clutch for current Gtk handling.)
  * And `audioformat="audio/mpeg"` for the default audio mime type.
  * While `default="Pop"` can specify which category is visible per default. (Will be retired in later versions. More a clutch for current Gtk handling.)
  * Other internal fields are listed in `channels/_generic.py`

To have a new plugin picked up, you need to copy/symlink the file into `/usr/share/streamtuner2/channels/`. It's imported from the `channels` module group automatically. Which allows relocatability, and later even local plugins. (Which is commonly unneeded featuritis though, so not yet implemented.)
