comment Group Datasets and take minimum/maximum
It should really be as simple as dataset[GroupBy["key"],Merge[{"text"->DeleteDuplicates,"min" -> Min, "max" -> Max}]]. Hope Merge will be improved in the future.

comment Multiple PlotLegends ignore NumberForm
I just tried typing "123[ESC]*[ESC]10[CTRL-6]^-1[CTRL-SPACE]" and the result was a string that displayed fine inside legends.

comment Multiple PlotLegends ignore NumberForm
I thing the alternative would be to make string like this "1.23[Times]\!(*SuperscriptBox[(10), (-1)])" automatically from ScientificForm, which I can get from just putting quotes around numbers manually. Obvious ways like ToString or TextString doesn't work as expected, so probably it requires just another implementaion of ScientificForm that would produce a nice string.

comment Creating centered inline cell in text cell
Are you sure it was created in the front end? Maybe it was imported from TeX, MathML or something. Or it was modified manually, adding GridBoxItemSize option there.

comment Symbolic scalar-by-matrix derivative
Until there is no actual tensor inside Tr it's just a symbolic expression, is up to you how to interpret it.

comment Symbolic scalar-by-matrix derivative
@cryo111 Wouldn't a matrix derivative of a matrix be a fourth rank tensor? Therefore its trace should be a matrix, not a scalar.

comment Different integral when used with assumptions
I would say it's a bug that there is not every conditional in the first result. But the results are the same if you assume this condition.

comment Too much whitespace in a GraphicsGrid containing Legended Plots
Adjust AspectRatio parameter inside your Plot function. For example AspectRatio -> 1. Maybe move your legend down.
