I'm the same switcher who posted the Dock question and I'll also be posting a DMG question in a follow up thread. As I was trashing folders and apps and other stuff while looking for an answer to my Dock problems, I discovered that Trash doesn't seem to act the same way my old PC recycle bin did. There is no function to restore anything; rather, it seems you just open the trashed item. (Also seems that you don't delete in Finder, you just "move to the Trash," is that the same?) Can you trash a program App and simply change your mind and reinstall it from the Trash? In that regard I tried Time Machine, but in the Apple tutorials I saw, it seemed that Time Machine is designed to restore files and folders, not applications. At least, it doesn't mention applications, so I was afraid to attempt to go back in time to just restore apps. I didn't want to go back to restore the entire system as there was work I had from yesterday which I wanted to keep.. I was led to believe that OSX/Unix doesn't have the same registry clutter remnants of programs which PCs do. Therefore, I thought you could simply open, trash, reinstall, trash, etc., at will, and not worry about your system becoming "PC like." So, what are the parameters/limitations of Trash and Time Machine as far as applications are concerned?
