comment Can I generate matrices with a constraint?
There will be examples in the docs. Maybe start with SparseArray

comment Can I use 'ItemStyle' in 'Grid' to specify the style of individual items?
sorry. this one: mathematica.stackexchange.com/questions/65356/…

comment Why DynamicModule does not plot the intersection region and does others?
Dynamic@TranslationTransform[pt][Vertices[Hexagon]]; does nothing. Dynamic updates pixels on the screen so whenever you have Dynamic@Something; nothing is being updated.

comment How could I have each new cell framed?
@kornaros yes. create a stylesheet and add the style. Plenty of examples on this site

comment Is it possible to import Spell Check and Hyphenation Rules from OpenOffice.org?
it should be possible but it would help if we could see the format of the dictionary you want to import

comment Is there a way to use Table[] without having to calculate my function twice?
Or SetAttributes[MyHugeMessyLongFn, Listable]; Transpose[{Range[5], MyHugeMessyLongFn@Range[5]}]

comment How to track Part of Symbol or How to symbolize Parts of Symbol without copying data
In the past I have done something similar to what @WReach suggests by creating a separate function to take the term with Head Part. Internally you assign a symbol to it and then track that symbol dynamically.

I get the same in 10.0.1 on OS X 10.10 -- definitely a bug

comment Insert the chapter number and title in a header or footer
You haven't provided enough information for anyone to give you a useful answer. Is your mathematical paper in a single notebook? How are the chapters partitioned? For example, if in a single notebook are the chapters all in separate sections etc etc

comment Equivalent command to the Maple indets command
@ChenStatsYu in that case use Maple but use Mma for the stuff that you don't feel that Maple does well, ... or cannot do

comment Equivalent command to the Maple indets command
@ChenStatsYu if Maple works for you and you understand it then stick to it. The time needed to switch to a rival product is rarely worth it if you are proficient in one of the other Ms

comment Equivalent command to the Maple indets command
@ChenStatsYu I think it is unfair to say it sucks at PDE solving. While i used to solve PDEs day in day out I have not done so for 10 years. There are still some problems that Mma cannot solve so you have to roll your own -- which I did cause NDSolve couldn't do it. Also NDSolve is an incredibly complex function to learn if you want to delve into it. Perhaps you should post a question if you are having a problem solving a PDE.

comment Conditional replace of a column
@kguler thanks. it is amazing what you can learn here. I never knew there was Threshold but it's been there since 8!

comment Equivalent command to the Maple indets command
@ChenStatsYu Mma is really poor with subscripted variables ..surprising for a software that many would say is the best computer algebra software. Mathcad is great for subscripted variable, easily the best on the market, but of course it has other deficiencies relative to Mma. As a Maple user you would know that Maple also is much better than Mma for subscripted variables, but not as good as Mathcad.

Yes good idea @RolfMertig. Do you have a more elegant explanation of the way Symbolize works? My attempted comment in my answer is rather clumsy. But it is still breakfast time here and my brain is foggy

comment How can I set Grid alignments using numbers?
@Kuba I couldn't agree more. However designed this stuff has never made layouts themselves. More to the point it seems that there has been a lack of coordination or project management in the design of Grid, Pane, Panel and so on. The result is that you end up just wasting a lot of time on this stuff

comment Notebook's WindowSize interference with contents' Dynamic ImageSizes
This sort of stuff is infuriating. Creating efficient working layouts in Mathematica is enough to drive you crazy.

comment Looping through a list partition
Note that in V9 there is also the function Developer`PartitionMap that will do what you require.
