AlgoWizard - Make drop down selection boxes for indicators multi-select / randomizable

Right now, it's not possible to randomize indicator parameters that are presented with a drop-down selection box. i.e. When the indicator's parameter has an annotation such as:

It would be great if these were randomizable. It would be even better if they were randomizable via a multi-select, so in the above example, I could choose Simple, Exponential, and Linear Weighted, but omit Smoothed.


While I'm at it, it would be great if, for general integer randomizations, if there could be multiple ranges defined via the freehand notation, i.e.: "10:60:10; 12:26:2"


It's probably too late to correct this issue (it would make retractive code behave unexpectedly), but it's kind of weird that the max value in the range is not inclusive. For example, why does 10:60:10 include 10,20,30,40 and 50, but not 60? 


Thank you.
