To install or uninstall an application is quote easy on Mac OS X. What a user need to do is to drag the application bundle to their disk, or drag the application to the trash can.
Unlike other applications, Input Methods are system level plug-ins, if a user want to install a new third-party Input Method software, he or she need to copy the files to the "/Library/Input Methods" or "/Library/Components" folder with system administrator privilege, and the developers may need to design a customized software installer to do it.
IMRemoval will automatically list all installed third-party Input Methods in a list and will allow its users to easily check the Input Methods they decide not to use anymore and click a button to quickly uninstall them.
