5.9. I hate the QJoyPad icon. Is there any way to change it?

Absolutely! Starting with version 3.3, QJoyPad stores its icons in $PATH/share/pixmaps/qjoypad (where $PATH is the install path used by given at install time, /usr/local by default) and actually comes with a few different icons to choose from. In that directory, there are two files, icon24.png and icon64.png which correspond to the small and large icons that qjoypad will use. These files are just links, and can be relinked to any png image of the appropriate size. Feel free to switch between the provided icons, change them, or make your own! QJoyPad should look how you want it to.
