It is good to see a plot with all data in V3.0, but I wonder whether it is possible to show the data of training and testing with either different color or symbols.
Another question is whether it is possible to update the information (like RMS errors) in 'Solution Info' panel for all data when 'Show combined data (training + testing)' plot is activated.
Also, in the Prediction for Plot options, it appears only one solution or all solutions can be chosen for showing the plot. It would be good if a few combined solutions can be selected by users for comparison.
