v0.6.2

• add oneColumnModeDomSort true|false to let you specify a custom layout (use dom order instead of x,y) for oneColumnMode setColumn(1) #713
• fix oneColumnMode to only restore if we auto went to it as window sizes up #1125
• editing in 1 column (or few columns) does a better job updating higher layout (track before and after and move items accordingly). Tracking item swap would be even better still. #1127
