comment accessing elements of nested list
+1 nice one :) How come you (and others) use ` ;; ` instead of All?

comment User Input Through Dynamic
Unfortunately your code only generates pink error boxes. Please ensure that you cut the entire code and paste. Have you worked through the examples in the Dynamic and DynamicModule docs as well as the advanced docs?

comment User Input Through Dynamic
In all likelihood you have Dynamic positioned in the wrong place but we need to see your code.

comment accessing elements of nested list
Just for something different: toy[[All, 2]] = toy[[All, 2, 2]]; toy

comment Finding x when sin(x) = -.758
ArcSin[-0.758] will give you an answer in radians.

comment Inconsistent image sizing with Grid and Row?
because you can paste images and use them as expressions just like anything else. The actual image size information is stored in the option ImageSizeRaw. When you say "GraphicGrid doesn't help either" what exactly do you want as the outcome?

comment Keeping Font Relative Size to Object/Graphics/Plot Object upon Reize
@iwantmyphd do you or do you not want the "natural" image size and aspect ratio that Mathematica chooses automatically for each plot?

comment Keeping Font Relative Size to Object/Graphics/Plot Object upon Reize
@SquareOne my comment was not addressed to you. I gave the same solution 23 hours ago but he rejected it and I deleted it. The OP does not understand the connection between image sizes and Scaled and aspect ratio.

comment Why does Mathematica remember print settings?
@Mr.Wizard the setting of that option when you print must be a Windows thing. On my Mac with 10.0.2 I just queued 50 copies and then again 5 copies with my printer off, the printing task is showing in the printer window but no change was made to the notebook options. I didn't go all the way to let the print job complete to see if that results in the local notebook options being changed.

@iwantmyphd yes. do you want circular disks or not, or will that be another change to your question?

@Mr.Wizard ok. but it look like it is about to get closed??

comment Keeping Font Relative Size to Object/Graphics/Plot Object upon Reize
@iwantmyphd you have to create the plots, obtain the aspect ratio used by Mathematica and via absolute options and then recreate the plots by adjusting the scaled length for disk in the y direction. Have you actually tried doing that yet?

It may also be more aesthetically pleasing to use SphericalRegion -> True

comment ControlType -> None Vs. Module inside Manipulate (i.e. making everything local)
The others have summarised #1. local variables are stored in the notebook. If you use Module there is a strong chance you will see pink boxes next time you open the notebook (until you re-evaluate). #2 you do not necessarily need to localise functions. Personally I never do. Read the docs for Initialization and SynchronousInitialization and study the examples.

comment Permanently rounding numbers/values to a given number of significant figures
Just so we are all clear, do you know the difference between the precision of reals used in Mathematica calculations and the print precision used for display?

comment Hiding a Manipulate slider
Note also that {seed, 1, 1000, 1, None} will suffice.

comment linear combination of successive elements in a list
This looks like a finite difference stencil. See detailed docs for NDSolve for higher order schemes ...if that is what you mean by different linear combinations

What do you mean exactly by not formatted?
