-- initial try to make it more asynchronus with multpible threads
+- move to an event based system
 
-- be more event based (vcsa sets POLLPRI)
-  http://scotdoyle.com/python-epoll-howto.html
-  Needed events:
-  screen update (vcsa sets POLLPRI)
-  plug input device (udev event)
-  screen changed (logind event, collides with screen update)
-  keyboard input (select, wait forever)
-  braille input (brlapi_readKey)
-  braille flush (timer, sleep)
-  Each event is watched in an own thread. This improves performance and reduce the load.
-  The event loop is to be done as "queue" since those are thread safe.
-  The threads are reading incomming data and add the events and data to the queue
-  the mainloop just reads the queue in an blocking way and executes the needed codepath with the data.
-  clean up the code for the events so that just the correct codepath is used:
-  - screen
-  - input
-  - new device
+- add initial multithreading/ multiprocessing support
 
-Settings:
-- configuration should be overwritable with parameter and alternative paths (Easy for contribution)
-Tutorial Mode:
-- navigate through a list of bound commands. speak binding and description.
+- support cli parameters
+  - add cli parameter for debugging "-d"
+  - add cli parameter to overwrite options "-o"
+  - add cli parameter to specify an settings.conf "-s"
