在 Ubuntu 10.04 上它无法干净地移除任务栏按钮，所以我让它把按钮留在那儿。
On Ubuntu 10.04 it wouldn't remove the taskbar button cleanly, so I made it leave it there.
不过既然你提了，这个功能哪怕乱一点也比没有强——尽管任务栏按钮暂时还在、点击一下才消失，这可能会让一些人困惑。
But now that you mention it, it's probably better to have the feature, even if it's messy, than not to have it, though it may confuse a few people when the taskbar button temporarily stays around but disappears if you click on it.
SVN 已更新。
