It would be nice to have a panel clock which, when clicked, can optionally run a program and only defaults to a simple calendar if no program is declared. This is discussed here on the forum:
If you have a number of "All Day" events on the same day, they are strung in a single line in Orage Day View. You can end up with a window that doesn't fit the screen. It would be better if the first line in the can be expanded vertically, with one All Day event on each line.
