I have used the method linked here to replace Unity with Xubuntu/Xfce and all went perfectly.
The only problem is the way the indicator plugin looks in the Xfce panel.
It is this version:
But it has some features from Unity, like the Menus from certain applications (VLC, Firefox etc) are displayed within the panel indicator and are not present in the application's window; also, the items from the indicator are in a bit chaotic order, also some tray icons are present in the "indicator" plugin, while others are in the other panel plugin "notification area".
After un-installing and then re-installing
xfce4-indicator-plugin is also crushing very often now.
