Windows 7 shows progress bar in the taskbar:
Notice the progress bar on the task bar of the Windows Explorer icon. It represents ongoing file operations. This is very nicely done. Subtle and intuitive. And finally I can rearrange the icons in the taskbar.
One of the features I like from – ahem – Ubuntu, is that it lets me shift the tabs of the task bar around. I just like to put my work on the left side and my nonsense on the right.
Windows Vista places it based on chronological order, left to right. And upon the restart of explorer.exe due to reasons I never fully understood, it auto arranges in an order not sensible to me at all.
Why why why!
