Nautilus in Plasma Environment

view story

http://askubuntu.com – I use Plasma Invirenment in Ubuntu 12.10. However I use Nautilus to view files. I have two problems with Nautilus: 1) It sometimes hides the Plasma Desktop. Because first run of Nautilus, opens a Desktop a default Folder View. (it's similar to Windows Explorer) 2) In Dolphin when an item is double clicked, an animation beside mouse pointer shows it will be opened soon. But in Nautilus there's not any animation. So sometimes I'm not sure if the double click is accepted. Is there any option to solve these problem? (HowTos)
