Con No Tabbing for Files or Shell instances
Idle's Interactive Python Shell and the Python Text Editor are separate window applications. Many would expect them to be unified together within a single window. To create a python program file, or module, the user first opens Idle (It's Interactive Shell), then the user goes to [File] and [New File] to open the Idle Text Editor. Plus, every time a new python file is opened, a new instance of Idle runs separately. So, there are no tabbed modules. That's clumsy approach that adds the complexity of juggling around many Idle instances.
