@shrx, Thank you. Why not to formulate this as a regular answer, so that I could up-vote it?

comment Plotting data with four variables; two labels for one of the axes
One obvious way to plot 4 parameters in 3D is to use a color scale for the fourth parameter. However, it is up to you to decide, how it is better to do it depending upon the sense of the plot. I might propose the idea to plot {x,(y1+y2)/2,z} as a 3D point and (y1-y2)/2 as a color. Check Menu/Help/DocumentationCenter/Plot3D/Options/PlotLegends to see how the color code can be added.

comment Do ShowGroupOpener and TitleGrouping suffice to control cell grouping?
Just to make sure, what are your problems are. Did you have any content under the cells you want to have a GroupOpener. The point is that if you have no content in the cells belonging to the group, the GroupOpener does not show up.

comment Using custom ticks with RegionPlot3D
It is not clear how you imagine to take the logarithm of the negative coordinates, say, in terms of x from -1 to 0?

comment How to simplify D[(1/2).m.(X[t]^2), {X[t]}]
It seems that the question is the result of s simple mistake in the basic syntax. I propose to put this question on hold.
