The recently released Windows 7 Beta (Build 7000) has several improvements in its GUI. Many of these features have been discussed at length in several blogs. Among other things, there is a deafult option to stack all program tabs in the taskbar keeping it from running out of space. There is a mouse-over feature that shows a preview of that program and brings that program to the foreground when the mouse is moved over that preview.
Then there is one tiny feature in the Windows Explorer that should have been implemented long time ago, but its good to finally see it in this release.
Organize >> Folder and Search Options >> View >> Use Check boxes to select items
Once that option is selected, a checkbox is displayed in front of the file each time the mouse hovers over it. This options overcomes the need to select individual files by keeping the ‘Control’ key press at all times.
This is one of the features I’d like to see ported over into Gnome for use in Linux distros.
