I would like to propose the following usability improvements for jitsi
1. Adjust the dialogs to more accurate Mac-friendly descriptions. In
the attached screenshot, the dialog "Clicking the X window button will
not exit the application, but only hide it. If you wish to exit the
application choose File/Quit." is Windows-centric and confuses MacOSX
(a) there is no "X" window button
(b) There is no "File/Quit" to choose
2. (not sure if this is a bug or expected behaviour) The "Jitsi"
application menu (top left) has no menu items. Clicking it simply
highlights it but does not open a menu. That should at least have the
standard "Properties", "Quit" etc menu items. As it is, I see no way
of reaching the "Properties" UI of jitsi.
