"""
Py3status plugin - shows current window title.
DEPENDENCIES:
Depends on i3-py!
pip install i3-py
CONFIG:
MAX_WIDTH - max title width
CACHED_TIME - in seconds
If payload from server contains wierd utf-8 (for example one window have something bad in title) - plugin will give empty output UNTIL this window will be closed. I can't fix or workaround that in PLUGIN, problem is in i3-py library.
