# GenericChannel implements the basic GUI functions and defines
# the default channel data structure. It implements fallback logic
# for all other channel implementations. Only `bookmarks` uses it
# directly.
#
# All other plugins don't have a pre-defined Notebook tab in the
# GtkBuilder description. They derive from ChannelPlugins therefore,
# which constructs and registers the required gtk widgets manually.
