Here are some screenshots of improvements made in the last Chrome (ok, Chromium.. :D) OS build:
File Manager open as a new tab (you should use CTRL+O to open files)
New folder name pop up
Folder "Test" created
You have to hit DEL if you want to delete the file
Folder "external storage" (note the curious date...)
Folders inside "external storage"
EFI boot files
Login screen when locked
Chrome OS is building up to be an amazing OS! I'm very convinced that Chrome OS will mark the begining of a new phase in operating systems.
And it's only Chrome OS v1.0. The party is just starting!
