I have a idea about file managers like nautilus or dolphin.<br><br>OpenOffice have a interesting action to change options while you click in different objects.For example , when you click on a table ,openoffice shows a new toolbar related with table facilities.<br>
<br>I think, it 's a good idea to implement this in file managers.For example when a user click on a mpeg file associed with video lan , nautilus show a toolbar with mpeg related options of videolan. .<br>
