A close button I personally don't see being useful, in the current state of how notifications are displayed. They come and go relatively quickly, and by the time you notice a notification to click the X it may have already disappeared.
Actions would be the obvious argument for a hidden option, but this has already been debated to death.
I can think of plenty of other options that would be nice though:
- Positioning and size
- Default expiration time
- Theming? Different colored backgrounds/font color, etc for those with different GTK themes
- Stacking notifications vs queuing. The default behavior is to queue up notifications and display them one after another, though with an active Gwibber you might have non-stop notifications appearing. The ability to have them stack on top of another, possibly with a limit of how many could be on the screen at once (as a user-configurable/gconf setting?) would be nice.
I have to admit, when I first saw notify-osd a few months ago, I hated it. But now that more applications are supporting the system, it feels *a lot* better -- not perfect, but better.
