I would be glad to see a Dynamic Regression Channel Facility implemented in Multicharts DT. A DRCF would automatically recalculate both the slope of the central Best Fit Regression Line and the Residual Standard Deviation as new prices flow in.  
As a consequence the "length" of the Regression Channel would increase while the starting point, selected manually, would stay fixed.
The current Regression Channel Facility in Multicharts DT is static and I find this to be inefficient, or indeed annoying. 
If I am waiting for a chart to reach a certain area in a Regression Channel it is tiring and boring to keep on re-drawing the RC. A good software should do that for me, like some competing software programs do.  
I think such an improvement would make Multicharts more user friendly and more useful.

PS: with Residual Standard Deviation I mean the Standard Deviation of Residuals ie of the differences between the values on the chart and the corresponding values on the Best Fit Regression Line
