My personal icon is gone.

What's happened to it? 

It appears this has come up quite a number of times (I have even wished this option existed for some of my worksheets).

There is no option to set the pixel size of a window for the plot as an option.  You must use your cursor to adjust the size of your window.  Even globally set the window size as I believe someone has mentioned before would also be a nice addition.

with(plots):
a:=[2.5,2.5,2.5,2.5,5,2.5,2.5,2.5,2.5];
b:=Matrix(3,3,a);
matrixplot(b)

Two corners have been drawn differently.  Shouldn't it be symmetric?  This appears to be a bug

Here's one view showing the sides cut away

and the other view of the other corners, rotated 90 degrees, to show what it should look like.

This is a view I would expect to see all around however the corner in the forefront and the one you can't see have been cut away as I've shown in the rotated view above.

I thought of a couple of new forum subtopics ... just an idea

Maple training beginner to advanced
 - not sure of the formalities here but this could be sub-forum-topic where one could go to get a better grasp of using maple however I think that comes with time anyways, as I said just a thought.  Lots of tutorials out there that do similar things anyways.

Using Maple in interesting ways
- This would be a subforum where users could post their finished projects.

It's funny that multiplication of a single number works on a list for each element but addition does not work the same way.

a:=[1,2,3]

3*a;
       [3,6,9]

3+a;
 error

You have to use zip(`+`,3,a) for it to work.  Is there not a simple way.  Why is that?
