The app currently operates in the following manner:

• Enable the slow quit functionality globally, except for the apps listed in whitelist.

I would like to propose an option which allows the opposite operation mode, i.e.

• Disable the slow quit functionality globally and enable it just for the apps listed in the whitelist.

The feature could be offered by simply adding a boolean switch such as invertList. This switch, which defaults to false (i.e. the current operation mode), when set to true, would only activate slow quit on the apps listed in the whitelist.

I already have an implementation of this feature in a local branch. If you are interested in adding this feature, please let me know, and I'll create a PR.
