comment Plot draws list of curves in same color when not using Evaluate
I am sorry to have misled you, I genuinely thought to have a 10.1 version: I was confused between $Version which returned 10.0 and $ReleaseNumber which returned 1 (and I concatenated these 2 to make 10.1) and I forgot to give a feedback . I upgraded now to 10.1 and these errors are gone but others are still present (please look at my latest question to which I gave my own answer since no answer was given after 4 months).

The other two methods also get the same error.

To which V10 version does your Mathematica 10 update apply? With MMA V10.1 and Plot[{1, ## &[2, 3], 4}, {x, 0, 1}, PlotRange -> {0, 5}, PlotStyle -> Thick]' I get an error (Identity::argx: Identity called with 2 arguments; 1 argument is expected`

comment Proper way to Plot a single function in two different styles?
@Simon Woods Your useful splitplot and splitsyle functions don't work anymore with MMA V10. Can it be easily updated ? Thanks

comment Fitting ellipse to 5 given points on the plane
Your ellipse definition is in fact the general equation of a conics - it is only an ellipse if the discriminant is negative. How does your answer take this restriction into account? Thanks

comment Fitting ellipse to 5 given points on the plane
With MMA V9 I do not get the right answer, for example f (-0.275185 + 1. x^2 + x (0.189022 + 0.566953 y) + 0.1281 y + 0.397124 y^2) == 0 is the equation of the ellipse which is returned. The parameter f is not resolved.

comment Finding length of intersection of two surfaces
On the contrary, to me your approach is quite elegant, concise with a flair for mathematics. And it works OK at least since MMA V5.

comment Combine a contour plot of a conic and an inset with an polygon such as all its vertices are on the conic
@Kuba Correct! I didn't think about using {ColorData["Legacy", "Banana"], EdgeForm[{Thick, Pink}], Opacity[0.15], Polygon[{a, b, c, d}]} in the Epilog instead of Inset... to achieve the same result. Inset obviously here was a wrong option and I guess that finding correctly the right Size would have been challenging and futile. I consider your comment as an answer.

comment How to efficiently drag points on a curve within a Manipulate
Michael I understand your idea: the locator is the point that is dragged.When I manipulate your solution it seems that the locator is always precisely on the conics.But after having modified your answer by Appearance -> Style[".", 40, Red]] the point can be slightly off the conic and this baffles me. Any idea why ?(By the way there is a comma too much in your last line). See youtube.com/watch?v=h9VCsX54irM which gave me the idea to reproduce something similar with MMA (but far for me to compare Geogebra with MMA) .

comment How to efficiently drag points on a curve within a Manipulate
@MichaelE2 Yes, you can update my question like that if you are sure that it can only be answered by restricting a locator (that I would like not to see). My question is more general and open I don't assume that restricting a locator is the only way, even if I started coding like that because I know of no other. Kuba gave me a nice answer based on restricting transparently a locator.
