I, like many, really would like a familiar "desktop" that can be used on any PC from a USB drive, yet I can't seem to find anything that provides this in a simple, elegant way. There are ways to mimic this, but they all seem to be too complex.
One thing that I wish was different is that PStart, PortableApps Menu, and most other "launcher" apps all use the same "menu" layout concept. Has anyone considered providing any alternate layouts? For example, I would like to see a "desktop" style layout. It would include all the great functionality of PStart or PortableApps Menu, but when you launch it, it would display a more familiar "desktop" window that resembles a PC desktop. It would contain folders (similar to PStart "Groups") and icons (similar to PStart "Items"). Heck, it could even have a user-selectable "wallpaper" image, and the "Start" button would display the launcher's menus. Yes, this adds complexity, but it would also provide a very slick "portable desktop" form.
