Xfce4 widget for displaying label/title of the currently focused AppVM

[rootkovska]

Some user might want to have a fixed indicator (e.g. in the main top panel) which always displays the color (and title?) of the currently focused AppVM. This is to prevent GUI spoofing attacks where a red-bordered malicious windows draws a fake green-border-password-prompting windows inside itself, hoping the user would paste some sensitive password there. There are many ways to work around such attacks, e.g. via activation of expose-like effect (Present Windows in KDE, or the somehow less convenient version via Alt-Tab in Xfce4), or by manually moving the sensitive window around the screen. Still this method might be slightly more convenient.
