How about an Integrated theme manager !!

:idea: How about considering an integrated theme manager in the prefences..

All the settings related to the appearance can be brought under this.
like:
* A theme manager.
* Decor styles,
* Color settings,
* Menu styles and Fonts,
* Scrollbar style,
* And a section for customizing the icons for filetypes,folders and others.

The theme manager should be able to
* Create a new theme from the current display settings.
* Open,Edit and Save themes (as a single theme file would be nice). so that it can be shared.

It would be really simple,easy and fun to play with if all these settings are brought under a single preferences section.
