You know I've always been partial to Konqueror on *NIX. Like Internet Explorer/Windows Explorer, the Internet half of it sucks. But the File manager bit is good! Has things like Tabbed Browsing. Even my old FTP clients had that. . . Something to think on as an improvement? Sorry, I suck at coding.
I like the filemanager style ROS has, but the backcolor of the puttons doesn't mach the window backcolor. They have different shade on grey, at least with my grapic adapter
