Hidden settings of Random Forest Learner

Hello!

In settings.xml of Random Forest Learner I see lines:

<entry key="columnSamplingMode" type="xstring" value="SquareRoot"/> 

<entry key="columnFractionPerTree" type="xdouble" value="1.0"/> 

<entry key="columnAbsolutePerTree" type="xint" value="10"/> <entry key="isUseDifferentAttributesAtEachNode" type="xboolean" value="true"/>

But I don’t see these parameters in configuration window of RF predictor.

Are they for compatibility?

Are you going to add them to UI later?
