Well, what the title says : is there any way to integrate Dropbox in the messaging menu like ubuntu one ?
Edit: Below is an image showing where Ubuntu One is on the messaging menu That is where I ask if I can put dropbox, NOT on the panel itself.
It is not possible (as far as I know) to move DP from its standard place in the traybar to the message menu. You can only add a shortcut in Message Indicator menu:
Open a terminal and type:
In the editor, type following text and save:
If you'd previously installed Dropbox, it's likely that the Dropbox daemon hasn't updated, which is part of why you don't see the indicator. To force the update, do this in a terminal window within GNOME:
You should then get a pop-up window prompting you about updating Dropbox.
