comment Nice scientific pictures show off
The tip of the arrow follows a Brachistochrone curve. If you flip the curve upside-down it is the curve of fastest descent, as first noted by Johann Bernoulli. In short, if you slide on such a curve you go from start to any point below it in shortest time. Animation of that fact will be a nice project.

comment How to have several overleftarrows of same height and length
@Werner it solves the height problem, but I still need to adjust the width/length so that arrows have the same length. I suppose I should use a \hphantom too. But when I do it does not center correctly.

comment How to have a visual indicator for the hyperref target in PDFLaTeX
Any indicator would do, anything like a --> to draw the attention of the reader to a specific portion of a page (while showing the whole page). This is essentially a "cursor" for the reader.

Hupfer: No, not a preview. I click, go the linked item page, on that page the location of the item I am linking to is pointed out by say a flashing arrow.

comment How to type a binomial tree with hanging branches
@LaRiFaRi Here B and C are separate entities. The tip of table is A, next row there are two elements B and C. After the second row each row has two additional elements on the left and right. The cells in the middle of each row gradually get to be longer. So [J1 J2] is one entity, so is [P1 P2], or [Q1,Q2] and so on. Each letter represents a relatively simple math formula.
