System panel and system menu

[tutanhamon]

What about following system menu accessible from bookshelf or any reader plugin. There may be some global key (like "Power key") for it. "View system messages" menu item provides access to /var/log/messages file viewer.

+---------------------------------------------------+
| [menu item 1] Lock                                |
| [menu item 2] Reboot                              |
| [menu item 3] Power down                          |
| [menu item 4] View system messages                |
+---------------------------------------------------+

Here is the idea extension: implement system panel visual application that shows a panel on the top (or bottom) with different info and provides access to the system menu also. Applications (like bookshelf, book readers or mp3 player) may use <space for applications data> to show own data.

Layout:

+---------------------------------------------+-------- +-----------+
|        <space for applications data>        | <clock> | <battery> |
+---------------------------------------------+---------+-----------+

Example:

+---------------------------------------------+-------- +-----------+
| Daniel Defoe - Robinson Crusoe      351/890 |  12:00  |       20% |
+---------------------------------------------+---------+-----------+

Extend also the system menu:

+---------------------------------------------------+
| [menu item 1] Lock                                |
| [menu item 2] Reboot                              |
| [menu item 3] Power down                          |
| [menu item 4] View system messages                |
| [menu item 5] Set clock                           |
| [menu item 6] System panel settings               |
+---------------------------------------------------+
| ...                                               |

BTW, the component may also show power-related warnings like ("low battery", "powered from USB", "charge completed" and so on).
