The applications in the Calligra Suite shares some common UI concepts that gives it a modern look better suited for the wide screens of today. One of them is that most formatting is done using dockers which are placed at the side of the windows instead of on the top. This makes more space available for the actual document contents and avoids opening dialogs on top of it. If the user chooses, s/he can rearrange the placement of the dockers around the document area or even tear loose them and let them float freely. The arrangement is saved and reused the next time Calligra is opened.
The Calligra project, being part of the KDE community, is dedicated to producing Free Software. Therefore you can download and install the Calligra Suite free of charge. The Calligra project only provides source code that can be build, but the suite can be installed on various operating systems using contributed installation packages.www.calligra.org/www.calligra.org/get-calligra/
