# title: New favourite category
# description: Introduces new bookmarks categories
# version: 0.3
# type: feature
# category: ui
# config: -
# priority: optional
# 
# Adds a "New favourite category..." under Station > Extensions menu.
#
#  · New categories will show up in the bookmarks channel under favourite.
#  · Also adds a "Bookmark to > …" context submenu.
#  · Still requires clicking/reloading the custom bookmark category.
#  · DND between bookmark categories is not supported.
#  · Subcategories can be removed (but requires exact name input).
#
# This is somewhat of a workaround. ST2 station lists are still unfit
# for bookmark management, because it wasn't a project goal as such.
