Keep Faith

DevilsPie：

A window-matching utility, inspired by Sawfish's “Matched Windows” option and the lack of the functionality in Metacity. Metacity lacking window matching is not a bad thing — Metacity is a lean window manager, and window matching does not have to be a window manager task.

Devil's Pie can be configured to detect windows as they are created, and match the window to a set of rules. If the window matches the rules, it can perform a series of actions on that window. For example, I can make all windows created by X-Chat appear on all workspaces, and the main Gkrellm1 window does not appear in the pager or task list.

这个工具还是很强大，，可以自定义很多程序启动时的属性，如是否最大化，在哪个桌面等等。。

比如让mplayer自动always On Top:
(if
    (matches (application_name) "^MPlayer")
    (begin
        (stick)
        (above)
    )
)
让QTerm到窗口3：
(if
    (matches (application_name) "^QTerm")
    (begin
        (set_viewport 3)
        (maximize)
    )
)
