+Includes a moduel tester which sends TCs in a queue and automatically

 Can be enforced/checked by using Pylint as an external program in PyCharm.
 Install it with pip and then install and set-up the Pylint plugin in PyCharm.
 
+There are a lot of features which would be nice, for example a GUI.
+The architecture of the program should allow extension like that without
+too many issues, as the sending and telemetry listening are decoupled.

 ## Import run configurations in PyCharm
 The PyCharm IDE can be used to comfortably manage a set of run configuations (for example tests for different
