Usability Improvements that have been agreed upon but have yet to be implemented are tracked here.
A dropdown-listbox to select the playlist layout used will to be placed above the playlist. Next to it there is a wrench-button (labeled "Configure layouts") which opens the layout configuration dialog.
The layout configuration dialog allows to add, remove and configure layouts. The general layout will be according to KDE design pattern for administering objects, third example. A reference implementation can be found in kmail when opening Settings -> Configure filters. The list has the following buttons: + (add layout) - (remove layout). Selecting a layout from the list on the left displays it's configuration in the configuration area on the right. The content of the configuration area remains the same as the current configuration dialog. The Dialog has Cancel, Apply (replacing the Preview button in the current dialog) and Ok buttons.
The current (svn) way of scrolling the widgets in the context view column is suboptimal since it is both horizontal and discrete whereas the widgets are laid out vertically and continuously. Using a normal scrollbar would raise the problem of having to scrollbars side by side when widgets have their own. gsteinert had the following idea to solve this:
To clearly distinguish it from internal scrollbars, the global scrollbar should look like the thumbnail bar e.g. in Okular, with a rectangle (with correct relative height) with icon representing each widget.

In order to avoid adding another element to the UI, the scrollbar should serve as a means to add, remove and move widgets to/from/across the context view. This would be done by pressing a wrench-button switches the scrollbar to "edit mode" and open a list of available windows to be dragged directly into the scrollbar. Widgets can be moved along the scrollbar in that mode as well as out of it to remove them. This would allow for a more direct way of manipulating the cv. The scrollbar has to change visually when the button is pressed to make clear where the configuration is done. This would make the horizontal nav/config bar obsolete.
