I just installed KStars 3.6.6 beta.
The new focus features are very intriguing to me. Any way, I noticed a minor issue in the EKOS UI with the new items in the Process tab.
When the Algorithm is changed from Linear 1 Pass to Iterative and back again to Linear 1 Pass, the Measure menu, including HFR, # of Stars, Fourier does not return and the selected Curve Fit is reset to Quadratic.

Other than that I look forward to trying out the new and improved focussing tools.
Thank you.
