    [] runtimeData.py
    [] screenData.py
    [] settingsData -> defaultSettings.py
General (Easy for contribution)
  [] wrapper script for running Fenrir to check if pypy3 exists, use python3 as fallback.
  [w] make fenrir runnable without root permissions
  [] make fenrir runable without settingsfile. fallback to defaults

Get information already in watchdogs insteed of mainloop (use eventloop to transport)
  [W] ScreenDriver
      [] split oldValues := newValues out to helper function
      [W] move processing of diff to own thread
      [W] move processing of encoding to own thread      

Imporove attribute handling

    https://github.com/jwilk/vcsapeek/blob/master/linuxvt.py

Improved Say all
  [] speech callbacks
  [] speech process by word
  [] all the text of all pages
  [] command to stop and place review cursor at this position

  [] place say all at clipboard buffer

Table review mode
  [] toggle table mode/ select headline
  [] next line
  [] prev line
  [] current line
  [] next cell
  [] prev cell
  [] current cell
  [] select field separator

Braille Support:
  [] brailleFocusMode:
    [] manual = no automatic toggle command used
    [] last = follow last used cursor
  [] print cursor in review
  [] print cursor in textmode
  [] word wrapping (if word does not fit print it at next page)
  https://docs.python.org/2/library/textwrap.html#textwrap.TextWrapper
  drop_whitespace = False
  replace_whitespace = False
  w.fill(i).split('\n')
  [] command toggle used cursor (in manual brailleFocusMode)  
  [] capture input from braile
  [] make routing keys assignable by keyboard
  [] make brailleTable configurable
  [] pkg-config --variable=tablesdir liblouis

Driver (screen, input):
[W] PTY Screen driver (to use gnome-terminal and other terminal emulators)
  [X] emulation
  [X] basic reading
  [W] attributes
  [X] detect colum/ lines
  [X] resize on colum / line change
  [W] make shell command configurable (or detect it)
  [W] stop emulation properly
  [] make pasteing text work again

  https://blog.konpat.me/pythons-pseudo-terminal-pty-examples/
[W] PTY Input driver
  [W] new event for byte shortcuts (escape sequences)
  [] create driver, set flag that it is used in emulation
  [] handle byte shortcuts
  [] detect shortcuts
  [] write/ consume them (controll it at all)
  [] create keyboard layout  
[] ATK input driver (don't grab on graphical interface)
  https://git.linux-a11y.org/AIT/pyatspi2/src/master/examples/keypress.py

Driver (speech):
[] talkey driver
[W] emacspeak driver
  https://pypi.python.org/pypi/ptyprocess#downloads 
[] Dectalk SpeechDriver (Easy for contribution, device needed - i dont own one)
  https://github.com/tvraman/emacspeak/blob/master/servers/obsolete/python/dectalk.py

Settings:
  [] write settings (Easy for contribution)
  [] menue for settings configuration (Easy for contribution)

Application Profiles (low priority):
- reimplement process detection without subprocessing
- fenrir is not able to detect the current application inside of screen.
    ps -e  -H -o pid,pgrp,ppid,tty,cmd
    http://stackoverflow.com/questions/24861351/how-to-detect-if-python-script-is-being-run-as-a-background-process/24862213
    fd = os.open("/dev/tty5", os.O_RDONLY )
    os.tcgetpgrp(fd)
- add perApplicationTrigger trigger
    per application commands
    per application onScreenChange
    per application onInput
- per application shortcuts
