Command Prompt...
Vijay is complaining about CMD.EXE being a real pain in the ass. I totally agree with him !! At school, when I see my friends typing all those weird command lines in their black screen under Unix, I always say them : "dude, you are a crazy guy ! how the hell can you do that ?!"
Anyway, after reading Vijay's Post, I had an idea, and here is the graphical representation of my idea:

The real problem of CMD.EXE is the difficulty of doing simple tasks like moving between folders, copy an entire folder, etc... Windows Explorer now let users do this really easily. I only use CMD.EXE to perform command line stuff like, for instance, generating a strong name key. So, I just browse to my project folder with Windows Explorer and then, I open up the "Command Pane" and type in the command to create my strong name key.
If a small app could provide this, that would be so cool ! If Microsoft could implement this directly into the real explorer.exe, it would be even cooler !
