Run/debug configurations are categorized into temporary and permanent.
A temporary run/debug configuration is automatically created every time you chooseor for an item without a permanent configuration. Temporary configurations can be saved as permanent.
Temporary configurations are marked with semi-transparent icons and are managed same way as
the permanent configurations.
By default, 5 temporary configurations are allowed per project. You can change this limit via the Edit Configurations dialog.
Permanent configurationA configuration of this type is explicitly created for a particular class or method. If there is no permanent configuration for an item, PyCharm automatically creates a temporary configuration for it, when you choose or on the context menu of this class or method.
