Currently, the task buttons in the taskbar of kicker (the buttons where each button represents a window in the user perspective) are sorted in column-major order, like this:

00 03 06 09 12 15
01 04 07 10 13
02 05 08 11 14 

It is needed and desireably for the user to be able to re-configure the order of the task buttons to be in row-major order, like this

00 01 02 03 04 05
06 07 08 09 10 11
12 13 14 15

The reasons are:
(1) Many users are accustomed to the row-major order. For example, the taskbar of Microsoft Windows is in row-major order by default.
(2) There user confusion is less when using row-major oder compared to column-major order (regardless of what the user is accustomed to): Suppose you remove the button "00" from the taskbar (e.g. the windows "00" is closed). Then the buttons are rearranged. In column major order, most buttons move upwards (e.g. button 08 goes upwards, button 07 goes upwards), but some buttons "wrap around" and move a long way downwards (and one step left) (e.g. button 06 goes two times downwards and one time leftwards). Likewise, in row-major order, must buttons move leftwards (e.g. buttons 11,10,09,08,07 go leftwards), but some buttons "wrap around" and move a long way rightwards (and one step up) (e.g. button 06 goes five times rightwards and one time upwards). The difference between column-major order and row-major order is the number of buttons which do not move "continuously" but do "wrap around". In our column-major order example, 5 buttons (03,06,09,12) wrap around, but in our comparable row-major order example, only 2 buttons (06,12) wrap around. Thus, the user is less irritated when using row-major order, because less buttons have a radical position change.
