I've recently switched from Ubuntu to Lubuntu and really appreciate it.
There are some features I'm missing from the toolset in Ubuntu, though, and one is from Nautilus.
When working with files, I use the detailed list a lot. What I'm missing is the ability to expand directories inside this view to work on the contained files, without the need to switch to the directory and then back to the containing one.
It would be great to have this ability in PCMan as well.
