The level window slider can be used to change the gray value window in order to adjust the intensities of the displayed image.
This slider works on the topmost visible image in the data manager. The user can use the context-menu of the slider to change the affected image.
However, using the render window manager, the three 2D render windows can display a different image each. Having several other images loaded in the data storage, it can be hard to identify the correct image in the context menu in order to change the gray value window for a certain image.
Therefore I would like to include another option (context menu?) which enables the user to select the render window, in which the level window slider should affect the topmost visible image.
Any concerns or other suggestions?
