The function multi_Class_Sampling allows the user to define only one band combination to be shown on the Leaflet window. However, for a better visual interpretation it would be very helpful if the user could define several band combinations within this function and if those combinations would appear in one Leaflet window where the user could switch between them in a similar way as in MiSa.C.
Only the current class (the one for which the threshold value has to be set) is displayed on the Leaflet window. However, for a better visual interpretation it would be helpful, if the user could see all already extracted classes and the currently considered class in one Leaflet window where the user could switch between these classes or could choose several classes to be displayed (also in a similar way as in MiSa.C).
If you stop at a certain step, close R and then continue with the next steps later, it would be less laborious if the user could just tell the function that the output folder contains the files needed to continue at a certain step.
I have three suggestions for improvement:
