Provide indication of an ongoing deployment

When I'm deploying an application (I tried with Guvnor 5.3 WAR), I click on "Enable" and then nothing happens. After a while (tens of seconds), the icon changes from red to green.
What should happen is that I get some indication (a dialog, for example) telling me "Deploying, please wait..." and when this dialog disappears, I know it's done.
Right now, I know nothing unless I watch the server logs.
