MouseButtons
A plugin that frees up the underused mouse in X-Plane 11 and let's you bind arbitrary commands to any of your mouse buttons and/or mouse wheel.
The plugin uses the same kind of .prf preference files as X-Plane for assigning commands to mouse buttons. Whenever you load up an aircraft, the plugin will look for a preference file with the same name as the aircraft inside the plugin's directory. In other words, when you jump into the Cessna 172SP the plugin will look for a preference file "X Plane 11/Resources/plugins/MouseButtons/Cessna 172SP.prf". If it can't find an aircraft-specific .prf file, it will look for a generic mouse.prf in the same directory.
Installation
Simply extract the .zip archive into the plugins directory of your X Plane 11 installation, e.g. X Plane 11\Resources\plugins.
