Fixed a bug that meant the cmus plugin crashed if nothing was being played.
Fixed a crasg bug in the news plugin. It seems that the BBC server is down,
hopefully it is because of a service outage and not them retiring the service.
Fixed a typo in the README and implemented Dzen pop up windows.
More work needs to be done, but basic geometry calculations to keep
the dzen windows on screen has been written.
Update README.md
Added menu command support to cmus as well as fixing as bug in _plugin's
positionDzen function.
Added more documentation to classes and functions. No new features
or bug fixes, so no version bump.
Fixed import issues so that i3situation can now be run with a debugger.
Added a new default configuration function, tidied up some documentation
and variable naming. This will be release 0.9.0
