Mac Keyboard shortcut keys don't work
When the launcher menu has the focus, it does not behave like native Mac apps. Keyboard shortcut keys such as CMD-Q (quit) don't work.
I guess it should be the same on other OSes.
This is still the case in Pharo Launcher 3.0.1. Of note, trying to quit Pharo Launcher by other methods like right-clicking on the Dock icon, pressing Cmd+Q with it selected in the Cmd+Tab switcher, etc. all fail as well—I think what's going on is that Pharo tries to respond directly to the Cmd+Q shortcut, but doesn't catch it correctly in all cases—but that's the wrong approach in the first place, there's an OS-level "quit requested" event of some kind that we should be catching and handling. Not a Cocoa programmer so I can't help further unfortunately.
