Ok, I have to admit when I first thought or heard of this feature in KDE 4.4, I wasn’t really excited. I thought.. centex . now why the hell would I want that. Then I started using it.. and found quite a few usage scenario’s for it. The first one, I realized right after I launched my VirtualBox. I had always hated how VirtualBox had a separate window for each VM and / or the main VirtualBox console, however, now with the Windows Grouping this is no longer an issue. Here’s a picture of the Virtual Box window open with 2 tabs. Here’s a close look at the tabs onlyAfter using it with Virtual Box, I realized that there may be other very simple usages of this, which include having 2 browsers open for website compatibility (I primarily use Opera, which some sites are not compatible with, and to combat the second window being open, I grouped my Opera and Firefox). I’m sure there are many other usages of the tabbed windows, that I’m overlooking. I’ve only used it for about 45 minutes and found those 2 cases. .I’d be interested in knowing what usability you think it will help you with. I will later write about adding KDE 4.4 onto openSUSE 11.2, probably when KDE 4.4 hits RC1.
