From version 6.4.4 the “Display as compact format” option in WatuPRO has two versions:

The difference between the old version 1 (default) and the new version 2 is best seen on this image:

Version 2 works very similar to the multi-column design of the questions but has no fixed number of columns and the choices are left aligned instead of spread equally on the whole width of the quiz area.

Version 3 added in WatuPRO 6.5.3.5 will be a mix of the two: question at left and answers floating at right as much as the space allows.
