* 15.06: Add a background to the tool additional controls Rescale the current layer number based on the maximum layer Add a text field style that can be used for generic text fields Implemented feature described by #30 Handle finished signal for the ReadMeshJob started from command line args Updated name in menu for firmware update Added exception handling to listen thread join Render a transparent ghost of the selection when things are selected. Fix for #29
