Plug-ins allow to add functionalities to the application.
The default folder is C:\Program Files\Lemony Pro\Plug-ins.
If you want to disable a plug-in temporarily, just remove it from the folder, or add an underscore to its name.
For example, change its name from Kio plug-in Microsoft Word.dll to _Kio plug-in Microsoft Word.dll.
Notice that if you re-install the software, all plug-in files will be created again.
To disable a plug-in permanently, you need to edit the configuration file.
