Just installed 12.04 on a laptop; I still have 10.10 on a server so I can compare directly and not just rely on my memory. Generally 12.10 is ok but the UI has taken a major step downhill.
I have reverted to gnome classic which goes most of the way to the old look and feel but the icons will not stay where I put them. They either go to the left or the right or the centre but I want them where I put them, so that I get reasonable spacing.
I have had a look at the settings via dconf-editor: I looked for something like 'snap-to-alignment' or the like but found nothing. I have a bad feeling that this may be some new feature of the underlying UI widget, i.e. in the source, rather than a configurable value.
The answer from here: How can I evenly space icons in the panel? is to use Active Window Navigator and stop fighting with the current panel.
Is that the best I can do?
