Users said they are used to the MITK mouse mode and would like to use them while working with the new multi widget. We assumed that the PACS mode would be preferred so it's not possible to change the mouse mode using the new multi widget. We should allow changing the mode via the properties as it can be done with the StdMultiWidget.
Additionally we could think about a new button in the rightmost new toolbar of the new multi widget to change the mouse mode quickly without opening the properties page.
