focus visualisation for KDE 4

[jan.muehlig]

Something that must be done on libs or qt level, but not in the hig:

it seems that there is no consistent way (or any at all) how the area
that has the focus is visualised in KDE. Take e.g. Kontact, and you use
the tab key: How do you know where the current focus is, and thus: where
e.g. your arrow keys effect.

it also seems that neither gnome nor windowsxp do this. gnome only marks
the button that would respond to "enter" action. If you take e.g.
nautilus, you never know when the focus is on the main pane (the folders
and document pane). same with windows.

macosx does it, by drawing a tiny rectangle around the pane that has the
focus. this is the behavior and visualisation i would suggest for kde4.

any comments? rejections? suggestions? implementation suggestions?
