Ubuntu :: Minimize Evolution To Tray?

With Lucid I gave evolution another try (actually the fourth time I installed a new Ubuntu version) and after some fiddling it worked (the first time, sadly). I like the idea to gather all "message" like things in one tray icon, so basically I like the indicator-applet. However, there is no way to customize it and many users complain about this. One particular issue is that evolution cannot be minimized to this tray icon. There are a lot of workarounds, all of them (to my knowledge) circumventing the indicator-applet and using an individual tray icon. But today, I found out how to do it. So... You want to use the indicator-message icon, but minimize evolution without an entry in the window-list? Devilspie has the "skip_tasklist" capability. So, install devilspie and create a script for evolution mail, e.g. $HOME/.devilspie/evolution.ds like this:

[Code].....

When evolution is started, the script pins evolution (so its available on all workspaces), enables skip_tasklist (so it is not shown in the window list), and minimizes it.
