# Author: Leon Bogaert <leon AT tim-online DOT nl>
# This Plugin Calls the libindicate bindings via python when somebody says your
# nickname, sends you a query, etc.
# To make it work, you may need to download: python-indicate and python-dbus
# Requires Weechat 0.3.0
# Released under GNU GPL v2
#
# 2010-09-22, Leon <leon@tim-online.nl>:
#     version 0.0.1 Intial release
# 
# @TODO: find out how to jump to buffer/line
# @TODO: how to communicate the click to weechat
# @TODO: decide what to do if a user clicks an indicator an then start typing:
#        * leave indicators alone
#        * remove indicators in the "neighbourhood"
#        * If a user cliks indicator: indactor dissapears
#        * On click group: remove all indicators
#        * When visiting buffer: remove indicators
