+6.) usage of 'import'
+
+Please avoid 'import *'.
+Use "from foo import bar" only if bar is clearly identifiable to belong to
+foo (e.g.: it's ok to "from Screens.MessageBox import MessageBox", but it's
+not ok to do "from os import path". Use "import os.path", then os.path.fnc.
+Of course "from os.path import *" is even worse.)

+7.-99.) Threads are bad.
