A couple of little things

1. I notice that there is no easily-identifiable way of creating a tooltip in the BeOS (Firefox seems to use a BWindow class, with the result that tooltips create a spurious blank entry on the Deskbar) so I suggest the inclusion of a BTooltip or BPopupHint class into Haiku's app_server.

2. There is no good way for a window to indicate on the Deskbar that it requires attention like Windows' flashing taskbar entry, OSX's bouncing icon or Linux's URGENT hint sent to the window manager (IM Kit includes a square-root symbol masquerading as a tick into the title of the IM window, but this is a per-application setting) so I recommend that three new forms of BMessage be accepted by the Deskbar - B_INFO_INDICATOR, B_ALERT_INDICATOR and B_WARNING_INDICATOR - which would display icons on the Deskbar indicating the level of urgency.
