I feel that the control panel has already become packed with all sort of
weird options that users tweak and then forget about.

Having half of the networking options in the control panel rather than
in the network neighborhood view is quite unintuitive. There's a battery
device icon on the frame, yet the power management settings are in the
control panel.

It seems that the practice of throwing everything in the control panel
has become a shortcut not doing proper UI design. We used to have a nice
spacial philosophy in which objects are represented by icons and
commands to manipulate them could be found next to them.

Now we have the concept such as the schoolserver which is invisible in
the UI and can be manipulated from the buddy menu and from the network
control panel. Yuck.

This is also being worked on, but don't expect all issues with the
datastore to be fixed in less than 5 years. Especially on jffs2 and on
the cheap microSD cards that ship with the XO-1.5. We must expect
corruption that can't be fixed just by clever algorithms.

For how long did MacOS ship with a hidden "repair desktop" function? Now
it's gone, but only because the desktop file is also gone :-)
