comment Working with CDF Deployment
On a Wolfram Blog posting it says "Enterprise Edition allows you to create EnterpriseCDF files, which provide enhanced capabilities that can be deployed via the free Wolfram CDF Player.". So I presume that Enterprise Edition produces a type of CDF that makes the free CDF Player behave as if it is CDF Player Pro.

comment How to use Feynman Slash notation?
I tried this on \[PartialD] — e.g. as in the Dirac equation — and the slash is placed after the derivative operator rather than through it.

comment Solving differential equation but keeping showing running
Use NDSolve, and to avoid problems at x == 0 don't include this point in the range of integration — e.g. put your initial condition at x = 0.001.

comment What is this Counts[] output format?
The documentation for Counts says (in the Details section) "Counts[list] gives an association whose keys are in the same order as they first occur as elements of list.", so you then look up Association and all is revealed. However, I agree with you that the documentation could be improved, e.g. Wolfram should add an explicit link to Association.

comment Computing an inexact derivative with some terms preserved in exact form
Use something like Rationalize[f[x], 10^-6] to force all the subexpressions in f[x] to be converted to exact quantities (within width-10^-6 bins).

comment Continuous background color of adjacent cells
I achieved this result by typing Hello and World in 2 successive text cells, then I selected the cell brackets, opened the option inspector, then I altered the values displayed at Cell Options / Display Options / CellMargins.

comment Continuous background color of adjacent cells
Cell["Hello", "Text", CellMargins->{{66, 10}, {0, 0}}, Background->RGBColor[0.87, 0.94, 1]] followed by Cell["World", "Text", CellMargins->{{66, 10}, {0, 0}}, Background->RGBColor[0.87, 0.94, 1]].

You can use the CellMargins option of Cell to do what you want.

I see you have now fixed the typo. I should really check that my code works AFTER I have finished doing all of my editing ...

comment Reduce gives wrong solutions
I wonder how this ties in with the documentation, which says "The result of Reduce[expr,vars] always describes exactly the same mathematical set as expr. ".
