The mouse controller had many limitations: * It was not per-device. * It was a long hard-coded list of events, which made its evolution annoying and scrolling the list boring. * It was starting at button 8, while the first buttons were supposed to be hardcoded interactions. And it stopped at button 12, while some device might have more buttons nowadays. See !386. * The "Grab event" does not seem to work in many cases, according to feedbacks. The new GimpModifiersEditor will now handle any button (except the first button, which is reserved for tools), you can even override or change default canvas actions (panning, rotation, etc.). It should not be limited with a max button number either (though I haven't tested with a device really having a lot of buttons since I don't have any such device but I did emulate huge button numbers on my stylus with xsetwacom and it did work well; hopefully I'll get feedbacks). And now it can even run custom actions. So basically it should deprecate the mouse controller as the modifiers editor can do everything the controller could, and more (unless I missed anything).
